Product Overview
Isopropyl Acetate 99.98% is a fast-evaporating ester solvent offered at Technical grade. At 99.98% concentration, this is a near-neat product — minimal residual moisture or acetic acid carryover — suited to coating formulation, chromatographic separation, and liquid-liquid extraction work where solvent purity directly affects process yield.
Alliance Chemical offers this product in sizes from 1-quart bottles through 55-gallon drums and 275- and 330-gallon totes, serving bench-scale trials and full production lines alike. Every shipment is classified as a Class 3 flammable liquid (per 49 CFR 172.101), and our warehouse team in Taylor, TX handles the DOT-required placarding, packaging, and documentation for each order.
Why This Concentration
At 99.98%, this Technical grade isopropyl acetate delivers the solvent strength needed for most industrial coating, cleaning, and extraction processes without the cost premium of an analytical-grade product. Technical grade means the product is manufactured and tested to consistent industrial specifications, but it does not carry a formal monograph or analytical-standard certification.
If your work demands a solvent traceable to a recognized analytical standard — reversed-phase HPLC method development, quantitative residue analysis, or pharmacopeia-referenced extraction — consider Isopropyl Acetate 99.98% ACS Grade, which carries that designation. For production-scale coating dissolution, parts cleaning, or process extraction where the 99.98% purity itself is sufficient and an ACS certificate is not required by your SOP, this Technical grade is the practical choice.
Chemical Profile
Isopropyl acetate (CAS 108-21-4, molecular formula C₅H₁₀O₂, molecular weight 102.13) is a clear, colorless liquid with an aromatic odor. It is lighter than water, with a density of 0.874 at 68 °F, and only slightly soluble — 1 to 10 mg/mL at 68 °F — so it separates cleanly in aqueous extraction setups. The vapor pressure profile reflects a moderately volatile solvent: 100 mmHg at 96.3 °F, rising to 760 mmHg at 192.2 °F, which gives formulators a predictable evaporation window between fast-flashing acetone and slower glycol ethers. Vapors are heavier than air and will collect in low-lying areas of a workspace. The flash point is 40 °F, placing it firmly in DOT Hazard Class 3 territory (per 49 CFR 172.101).
Industrial Applications
Isopropyl acetate at this purity serves several distinct process roles:
-
Coatings and adhesives formulation. Dissolves a wide range of resins — nitrocellulose, acrylics, vinyls — and evaporates at a controlled rate that promotes smooth film formation without blushing. Formulators use it as a primary solvent or as a blend component to tune viscosity and dry time in lacquers, inks, and pressure-sensitive adhesives.
-
HPLC mobile phase. The 99.98% purity makes it a practical choice for reversed-phase chromatographic separations of organic compounds. Its low UV cutoff and clean baseline reduce ghost peaks. Analysts running routine industrial QC often select Technical grade here; critical quantitative or pharmacopeial work may call for the ACS Grade.
-
Liquid-liquid extraction. Low water miscibility and moderate density let it partition cleanly against aqueous phases, making it effective for isolating intermediates in chemical manufacturing.
-
Industrial cleaning. Cuts greases, waxes, and cured adhesive residues from metal and plastic substrates. Evaporates without leaving a film, reducing the need for a secondary rinse step in degreasing lines.
Handling & Storage
This product carries the GHS signal word Danger (per the product's GHS classification). The governing hazard statements are:
-
H225 — Highly flammable liquid and vapor (per the product's GHS classification)
-
H319 — Causes serious eye irritation (per the product's GHS classification)
-
H336 — May cause drowsiness or dizziness (per the product's GHS classification)
Vapors are heavier than air and will travel along floors to ignition sources. Eliminate all open flames, sparks, and hot surfaces in the work area. Provide mechanical ventilation or use the product inside a fume hood to keep vapor concentrations below occupational limits.
Wear chemical splash goggles and nitrile or butyl-rubber gloves when handling. If prolonged or repeated skin contact is possible, use a chemical-resistant apron. Store in tightly closed containers — HDPE or glass — in a cool, well-ventilated area segregated from strong oxidizers and concentrated acids. Keep containers sealed when not actively dispensing to minimize evaporation losses and vapor accumulation.
Hazmat & Shipping
Isopropyl acetate is regulated for transport as a flammable liquid. The classification details that govern every shipment from our Taylor, TX facility:
-
UN Number: UN1220 (per 49 CFR 172.101)
-
Proper Shipping Name: Isopropyl acetate (per 49 CFR 172.101)
-
Hazard Class: 3 — Flammable Liquid (per 49 CFR 172.101)
-
Packing Group: II (per 49 CFR 172.101)
Our warehouse team selects UN-rated packaging, applies the required Class 3 diamond labels, and prepares shipping papers for every outbound order. Packing Group II reflects the relatively low flash point (40 °F) and requires intermediate-level packaging integrity.
Documentation
A Safety Data Sheet ships with every order. SDS documents are available in English, Spanish, French, and Japanese. A Technical Data Sheet is also provided. Lot-specific Certificates of Analysis are available upon request, documenting the analytical results for the specific production lot you receive.
Why Buy from Alliance Chemical
This product is available from 1-quart containers through 330-gallon totes, with SDS, TDS, and lot-specific COA documentation — so whether you need a single quart for a bench trial or a tote for a coating line, the supporting paperwork ships with it. Alliance Chemical has served over 50,000 customers since 1998, and every hazmat shipment — including this Class 3 flammable — is reviewed under our DOT compliance program overseen by Andre Taki, DOT Hazmat Specialist (USDOT #2188383).
