Product Overview
n-Propyl Alcohol ACS Grade — also sold as 1-propanol or propyl alcohol, CAS 71-23-8 — is a clear, colorless, water-miscible solvent alcohol supplied to laboratory reagent grade. It is a fast-working polar solvent with an odor similar to ethanol, and it is flammable: it carries the signal word Danger (per the product's GHS classification) and ships as a Class 3 hazmat. we distribute it in our Taylor, TX warehouse and ship it daily in DOT-compliant packaging, from single quarts for the bench to 330-gallon totes for production.
The buyers who order this SKU are analytical labs running HPLC, pharmaceutical extraction operations, coatings formulators, and industrial maintenance teams that need a reliable degreasing solvent. If your process is sensitive to trace impurities — chromatography, API extraction, synthesis feedstock — this is the grade to specify.
Why This Concentration
ACS Grade means the material is supplied to laboratory grade tier, and that distinction matters most where impurities show up in your results. In reversed-phase HPLC, solvent contamination appears directly in your baseline. In pharmaceutical extraction, whatever is in the solvent ends up concentrated in the extract. For those applications, a technical-grade alcohol is a false economy: you save on the drum and pay for it in rework, ghost peaks, or a failed release test.
If your use is straightforward cleaning or degreasing where trace organics are irrelevant, ACS Grade still works — it simply gives you headroom you may not need. Buyers running both a lab and a plant floor often standardize on ACS Grade anyway to keep one SKU, one SDS, and one storage protocol. Each lot ships with a certificate of analysis, so your QC team can verify what arrived instead of assuming.
Chemical Profile
n-Propyl alcohol is a clear colorless liquid with a sharp, musty odor similar to ethanol and rubbing alcohol. It is fully miscible with water, with a density of 0.803 at 68 °F — less dense than water, so it will float — which works out to roughly 6.5 lb per gallon for freight planning. Vapor pressure is 44.98 mmHg, so open containers lose product and load the air quickly. The flash point sits at 53–77 °F, meaning this liquid can form ignitable vapor at ordinary room temperature, and it autoignites at 700 °F. Vapors are heavier than air, collect in low spots, and mildly irritate the eyes, nose, and throat. The molecule itself is C3H8O, molecular weight 60.10, CAS 71-23-8.
Industrial Applications
These are the real, established uses we ship this product for:
-
HPLC mobile phase — 1-propanol serves as a mobile-phase component in reversed-phase high-performance liquid chromatography, where its polarity and miscibility with water let it tune retention and separation of organic compounds. ACS Grade designation keeps the baseline clean.
-
Pharmaceutical extraction — used as an extraction solvent for pulling active ingredients from plant material. The solvent's purity carries straight through to the extract, which is why extraction buyers specify ACS Grade.
-
Chemical synthesis intermediate — a feedstock and intermediate in the production of esters, halides, and other downstream chemicals. Consistent lot-to-lot quality means consistent reaction behavior.
-
Paints and coatings — a solvent in lacquer formulations, dye solutions, and coating systems, where it dissolves resins and controls application and dry-down behavior.
-
Industrial cleaning and degreasing — an effective cleaner for flux residues, oils, and polar soils on parts and equipment, evaporating without leaving water behind.
Handling & Storage
Treat this product as the flammable liquid it is. The GHS signal word is Danger, with hazard statements H225 (highly flammable liquid and vapor), H318 (causes serious eye damage), and H336 (may cause drowsiness or dizziness) (per the product's GHS classification). H318 deserves emphasis: a splash to the eyes is a serious injury, not an irritation. Wear chemical splash goggles and compatible gloves whenever you transfer it, and work with ventilation — the vapors are heavier than air and will pool at floor level.
Store it cool, dry, and well-ventilated, away from heat, sparks, and ignition sources. Keep it clear of strong oxidizers and acids. HDPE and glass are compatible container materials. Keep containers tightly closed when not in use — with a vapor pressure of 44.98 mmHg, an open drum is both a product loss and a vapor hazard. Bond and ground containers during transfers. Our warehouse crew handles this material under these same rules every day; this guidance is reviewed by Andre Taki, DOT Hazmat Specialist.
Hazmat & Shipping
This product ships as regulated dangerous goods under the proper shipping name N-PROPANOL (per 49 CFR 172.101), UN1274 (per 49 CFR 172.101), Hazard Class 3 — flammable liquid (per 49 CFR 172.101), Packing Group II (per 49 CFR 172.101). We pack every order in UN-specification packaging with correct marks, labels, and shipping papers before it leaves our dock. You receive a shipment that is compliant on arrival — no relabeling, no paperwork gaps, and no surprises at receiving. Alliance Chemical charges hazmat fees may apply.
Documentation
A Safety Data Sheet ships with every order, available in English, Spanish, French, and Japanese — useful if your EHS program covers multi-language facilities. A lot-specific Certificate of Analysis is available for every shipment, so your QC team can confirm the material against the lot actually received. A technical data sheet is also available for spec review before you order.
Why Buy from Alliance Chemical
We are a chemical distributor and hazmat shipping operation, and this product moves through our Taylor, TX warehouse daily. Our crew packs Class 3 flammables to DOT specification as routine work, not an exception, and our shipping and handling guidance is reviewed by a DOT Hazmat Specialist. You get the same material whether you order one quart or a 330-gallon tote, with the SDS and lot COA to prove it. Orders ships under applicable requirements from Taylor, TX, with hazmat fees may apply added. If you are unsure whether ACS Grade fits your process, contact us before you order — we would rather answer the question than process a return.
