Also sold under the names isopropanol and 2-propanol, it is a workhorse solvent for usp extraction, electronics and equipment cleaning, and paint and coatings formulation. Buyers who specify the USP Grade descriptor in their purchasing workflows — usp, cosmetic, and personal-care supply chains in particular — will find that designation on this listing, along with a lot-specific Certificate of Analysis. This is pure isopropyl alcohol, not a denatured blend.\u003c\/p\u003e\u003ch2\u003eWhy This Concentration\u003c\/h2\u003e\u003cp\u003eAt 91%, the remaining fraction is water. That matters two ways. First, the water content slightly moderates the flash-off rate compared with higher-strength IPA, which some wipe-down and extraction workflows prefer. Second, if your process is water-sensitive — certain coatings systems or moisture-critical electronics work — confirm that the water fraction is acceptable before you commit to a drum. The USP Grade descriptor is a procurement distinction: buyers in regulated supply chains commonly request it when a usp-grade solvent will not clear their vendor requirements. Review the lot COA and SDS against your own specification before use. Regardless of grade, the 53 °F flash point makes this a flammable liquid, and every pack size we sell ships under the same Class 3 rules (per 49 CFR 172.101).\u003c\/p\u003e\u003ch2\u003eChemical Profile\u003c\/h2\u003e\u003cp\u003eIsopropyl alcohol carries the formula C3H8O with a molecular weight of 60.10, CAS 67-63-0. It is a volatile, colorless liquid with a sharp, musty odor familiar from rubbing alcohol. Density is 0.818 g\/mL at 20 °C — roughly 6.5 pounds per gallon, which is worth knowing when you are staging drums or calculating freight weight on a 55 gallon order. Vapor pressure runs 33 mmHg at 68 °F and 40 mmHg at 74.8 °F, so open containers lose product quickly and vapors accumulate low, because they are heavier than air. Water solubility is 100 mg\/mL or greater at 72 °F; in practice it blends freely with water in cleaning and extraction dilutions. Flash point is 53 °F.\u003c\/p\u003e\u003ch2\u003eUSP Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSP extraction:\u003c\/strong\u003eIPA serves as a liquid-liquid extraction medium for isolating intermediates. The 91% cut dissolves a wide range of organics while staying fully miscible with aqueous phases.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectronics and equipment cleaning:\u003c\/strong\u003eIt lifts flux residues, oils, and fingerprints from boards, contacts, and usp glassware, then evaporates without leaving an oily film.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePaints and coatings:\u003c\/strong\u003eFormulators use isopropanol as a solvent and thinner in lacquer systems and coating formulations, where its evaporation profile helps control application properties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSP solvent work:\u003c\/strong\u003eLabs use IPA as a mobile-phase component in reversed-phase chromatography and as a general bench solvent for spectroscopy sample preparation and rinsing.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAcross all of these, the buying decision usually comes down to grade descriptor, water tolerance, and container size — not exotic performance differences. If you run high volumes, moving from 5 gallon pails to 55 gallon drums or bulk totes cuts your per-gallon cost and your receiving frequency.\u003c\/p\u003e\u003ch2\u003eHandling \u0026amp; Storage\u003c\/h2\u003e\u003cp\u003eThe signal word for this product is Danger. It is a highly flammable liquid and vapor (H225), causes serious eye irritation (H319), and may cause drowsiness or dizziness (H336) (per the product's GHS classification). Treat every transfer as an ignition risk: ground and bond containers, keep the work area ventilated, and eliminate open flames, sparks, and hot surfaces. Vapors sit low and travel, so ventilate at floor level, not just overhead. Wear splash goggles and chemical-resistant gloves when dispensing. Store in a cool, ventilated flammables area in closed, compatible containers — HDPE and glass both hold up well — away from strong oxidizers and acids. Keep containers tightly closed between uses; this product evaporates readily and you will lose inventory to an open bung.\u003c\/p\u003e\u003ch2\u003eHazmat \u0026amp; Shipping\u003c\/h2\u003e\u003cp\u003eThis product ships as regulated hazmat under the proper shipping name Isopropanol, UN1219, Hazard Class 3, Packing Group II (per 49 CFR 172.101). That classification governs how our team packs, marks, labels, and documents every quart, pail, drum, and tote that leaves our dock. Your carrier's fees, routing, and delivery options are driven by that same Class 3 designation, so plan receiving accordingly — flammable-liquid shipments require a receiver who can accept hazmat freight. We prepare the shipping papers and hazmat markings on our end; that is our daily work, not an occasional exception.\u003c\/p\u003e\u003ch2\u003eDocumentation\u003c\/h2\u003e\u003cp\u003eEvery order ships with the Safety Data Sheet, and we publish the SDS in English, Spanish, French, and Japanese — useful when your EHS docs need to cover a multilingual crew. A lot-specific Certificate of Analysis is available for the material you receive, so your QC lead can review the actual lot rather than a generic spec sheet. A USP Data Sheet is also available on request. If your vendor-qualification process needs these docs before purchase, ask — sending paperwork ahead of a PO is routine for us.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Alliance Chemical\u003c\/h2\u003e\u003cp\u003eWe offer this product in a genuinely wide range — 1 quart bottles for the bench, 1 and 5 gallon containers for pilot work, 15 and 55 gallon drums for production, and 275 and 330 gallon totes for bulk consumption — every size packed and shipped under the same UN1219 Class 3 discipline (per 49 CFR 172.101), with SDS and lot COA documentation included in the workflow.
