Product Overview
Cyclohexanone ACS Grade is a colorless to pale yellow flammable liquid classified as UN1915. It carries a distinctive odor reminiscent of peppermint and acetone — operators on our dock recognize it before they read the label. ACS Grade means this product meets the purity specifications set by the American Chemical Society for reagent-grade chemicals, making it suitable for analytical work, HPLC mobile phases, and demanding synthesis processes where trace impurities can skew results.
we distribute this product in our Taylor, TX warehouse and ship it daily under full DOT hazmat compliance. Buyers are typically analytical labs running chromatography, coatings formulators dissolving resins and polymers, and chemical manufacturers using cyclohexanone as a reaction intermediate. Every container ships with documentation and proper hazmat labeling.
Why This Grade
ACS Grade exists for a specific reason: reproducibility. When you run an HPLC separation or use cyclohexanone as an extraction solvent in pharmaceutical work, trace-level contaminants change your results. ACS Grade gives you a defined purity ceiling that your QC team can reference against a published specification — the same specification your method validation was built on.
If your application is industrial solvent work — dissolving coatings, cleaning equipment, or blending formulations where analytical-grade purity is unnecessary — a technical grade would cost less per liter. But if your SOP calls for ACS Grade, substituting down introduces a variable your process wasn't validated against. Match the grade to the method.
Chemical Profile
Cyclohexanone (C6H10O, CAS 108-94-1) has a molecular weight of 98.14 g/mol. It presents as a colorless to pale yellow liquid at room temperature with an odor reminiscent of peppermint and acetone. The density is 0.945 at 68 °F, making it less dense than water — it will float on a water surface, which matters for spill response. Solubility in water runs 50 to 100 mg/mL at 64 °F: partially miscible, not fully water-soluble. Vapor pressure is 5.2 mmHg at 77 °F and rises to 10 mmHg at 101.7 °F. That moderate vapor pressure means noticeable off-gassing at room temperature, especially in warm warehouses — adequate ventilation is not optional. Flash point is 111 °F, placing it squarely in the flammable liquid category.
Industrial Applications
Cyclohexanone ACS Grade serves a range of analytical, industrial, and manufacturing processes. Below are the primary uses we supply into:
-
HPLC Mobile Phase — In reversed-phase high-performance liquid chromatography, cyclohexanone functions as a mobile phase component for separating organic compounds. ACS Grade purity matters here because trace impurities produce ghost peaks or baseline drift that compromise quantitation. Labs running routine analytical methods rely on a consistent, grade-specific supply.
-
Solvent for Coatings and Adhesives — Cyclohexanone dissolves a wide range of organic compounds, making it effective in paint, coating, and adhesive formulations. It solvates resins and polymers that resist lighter ketones, and its moderate evaporation rate gives formulators a workable open time before the film sets.
-
Chemical Synthesis Intermediate — Cyclohexanone is a precursor in the production of nylon and other synthetic fibers. It enters the caprolactam pathway, where the ketone undergoes oximation and Beckmann rearrangement. Manufacturers drawing on ACS Grade for this work are typically running bench-scale or pilot processes where purity control affects yield.
-
Extraction Solvent — In pharmaceutical processing, cyclohexanone serves as an extraction solvent for isolating active ingredients from plant materials and reaction mixtures. Its solvency profile and boiling point make it practical for liquid-liquid extraction steps.
-
Laboratory Cleaning Agent — Cyclohexanone dissolves residues that lighter solvents leave behind on glassware and equipment. It is used in research labs for cleaning between experiments, particularly when residues from coating or polymer work have built up.
Handling & Storage
Cyclohexanone carries a GHS signal word of Danger (per the product's GHS classification). The full hazard profile includes:
- H226 — Flammable liquid and vapour (per the product's GHS classification)
- H302 — Harmful if swallowed (per the product's GHS classification)
- H312 — Harmful in contact with skin (per the product's GHS classification)
- H315 — Causes skin irritation (per the product's GHS classification)
- H318 — Causes serious eye damage (per the product's GHS classification)
- H332 — Harmful if inhaled (per the product's GHS classification)
- H335 — May cause respiratory irritation (per the product's GHS classification)
Store in a cool, well-ventilated area away from heat sources, open flame, and direct sunlight. Containers should be HDPE or glass — cyclohexanone can attack certain plastics. Keep it segregated from strong oxidizers and strong acids to prevent hazardous reactions. Moisture and light degrade product integrity over time, so keep containers sealed when not dispensing.
PPE requirements are straightforward: chemical-resistant gloves (nitrile or butyl rubber), splash-proof safety goggles or a face shield given the H318 serious eye damage statement, and respiratory protection if ventilation is insufficient to keep vapor concentrations below exposure limits. The vapors are heavier than air, so they accumulate in low points — ground-level ventilation is as important as overhead exhaust.
Hazmat & Shipping
Cyclohexanone ships as a regulated hazardous material. Every outbound container from our Taylor, TX facility is packaged and labeled to DOT specifications:
-
UN Number: UN1915 (per 49 CFR 172.101)
-
Hazard Class: 3 — Flammable Liquid (per 49 CFR 172.101)
-
Packing Group: III (per 49 CFR 172.101)
-
Proper Shipping Name: Cyclohexanone (per 49 CFR 172.101)
Packing Group III indicates a lower degree of danger within the flammable liquid class, but DOT compliance still governs every step: proper inner packaging, absorbent materials, outer container selection, diamond placards on LTL shipments, and a complete shipping paper set. We handle all of this — your order arrives labeled, documented, and ready for your receiving dock.
Documentation
A Safety Data Sheet ships with every order. SDS documents are available in English, Spanish, French, and Japanese. This product carries its listed grade designation; confirm the lot-specific COA against your requirements. If you need documentation before placing an order, contact us and we will send it.
Why Buy from Alliance Chemical
We are a hazmat distributor, not a marketplace. Cyclohexanone ACS Grade ships from our warehouse in Taylor, TX — packed by our crew, labeled to DOT spec, and on a truck within 1-2 business days for most orders. Shipping and handling guidance for this product is reviewed by Andre Taki, DOT Hazmat Specialist. We carry the product in sizes from 1-liter bottles for bench work up through 55-gallon drums for production use, and we do not charge hazmat fees. When you need documentation, responsive communication, and an operator who understands flammable liquid logistics, that is what we do.
