Product Overview
Glycol Ether EE ACS is ethylene glycol monoethyl ether (CAS 110-80-5), a clear, colorless liquid solvent with a sweet, ether-like odor, offered in the ACS grade designation. It is a workhorse oxygenated solvent: it dissolves a wide range of resins, oils, and organic residues while staying miscible with water, which is why it shows up in coatings lines, industrial cleaning processes, analytical labs, and chemical processing operations.
The buyers we pack this for are QC and analytical labs running HPLC methods, coatings formulators who need a slow-evaporating coupling solvent, and plant maintenance or manufacturing teams degreasing equipment. Pack sizes run from 1 quart bench bottles to 55-gallon drums and 275/330-gallon totes, all offered to order from our Taylor, Texas warehouse.
Be clear-eyed about the hazard profile before you order: this material carries the signal word Danger, including reproductive toxicity hazard statement H360FD (per the product's GHS classification). It belongs in an engineered industrial or laboratory setting, not general-purpose use.
Why This Concentration
The ACS designation on this listing matters for procurement, not chemistry. Analytical labs, instrument methods, and quality systems frequently specify an ACS-grade solvent on purchase orders so the material entering the workflow matches the designation their SOPs call for. If your HPLC method, specification sheet, or customer audit language asks for an ACS-grade glycol ether, this is the listing that answers it.
If you are running bulk cleaning or coatings processing where the purchase order does not call out a grade designation, the same chemistry does the same solvent work — the deciding factors become pack size, documentation needs, and price per gallon. Review the TDS and the lot-specific COA against your own specification before you commit a production run; a grade label on a listing is a procurement descriptor, and your acceptance criteria should always be confirmed against the actual lot documentation.
Chemical Profile
Ethylene glycol monoethyl ether is a clear, colorless liquid with a sweet, pleasant, ether-like odor. The formula is C4H10O2 with a molecular weight of 90.12, CAS 110-80-5. It is less dense than water — 0.931 at 68 °F — so it floats on water rather than sinking, and it is highly water-soluble at greater than or equal to 100 mg/mL at 64 °F. Vapor pressure is a modest 3.8 mmHg at 68 °F, which is why it evaporates slowly compared to light solvents and lingers in a coating film long enough to do coupling work. Two facts drive how our warehouse crew treats it: the flash point is 120 °F, which puts it in Hazard Class 3 as a flammable liquid (per 49 CFR 172.101), and its vapors are heavier than air, so vapor accumulates low — at floor level, in sumps, and in pits — rather than dispersing upward.
Industrial Applications
-
HPLC mobile phase work. Analytical labs use this solvent as a mobile phase component in reversed-phase high-performance liquid chromatography, where its water miscibility and solvency for organic compounds make it useful in method development and routine separations. Confirm compatibility with your column and detector before switching solvents.
-
Paints and coatings. Formulators use it as an active solvent and coupling agent in coatings systems. Its low vapor pressure means slow, controlled evaporation, which helps film leveling and keeps resin systems open longer during application.
-
Industrial cleaning. As a cleaning agent, it cuts oils and greases from parts and equipment while rinsing away with water — a practical combination for manufacturing maintenance where a straight hydrocarbon solvent leaves residue and a pure aqueous cleaner does not touch the soil.
-
Chemical processing. It serves as an intermediate in the synthesis of downstream chemical compounds, purchased in drum and tote volumes by processors feeding continuous or batch operations.
Handling & Storage
This product carries the signal word Danger. The hazard statements are H226 (flammable liquid and vapor), H302 (harmful if swallowed), H331 (toxic if inhaled), and H360FD (may damage fertility; may damage the unborn child) (per the product's GHS classification). H360FD is the one that should shape your site's exposure controls: this is a solvent to handle with engineering controls and a real ventilation plan, not just gloves and hope.
Operator practice from our dock and from the SDS: wear chemical-resistant gloves and safety goggles; work with mechanical ventilation to keep inhalation exposure down, remembering the heavier-than-air vapors settle low. Store cool and dry, away from heat sources and direct sunlight, and keep it segregated from strong oxidizing agents and acids. HDPE and glass are suitable container materials. With a 120 °F flash point, treat it under your facility's flammable-liquid storage rules — grounded containers, no ignition sources in the storage area.
Hazmat & Shipping
This product ships as regulated hazardous material. The proper shipping name is Ethylene glycol monoethyl ether, UN1171, Hazard Class 3, Packing Group III (per 49 CFR 172.101). Our team packs Class 3 flammable liquids daily: UN-spec packaging, correct marks and labels, and shipping papers prepared to the regulation. If you are receiving drums or totes, confirm your facility is set up to receive Class 3 material before the freight arrives — that conversation is cheaper before the truck shows up than after.
Documentation
A Safety Data Sheet ships with every order and is available in English, Spanish, French, and Japanese — useful when your EHS program or workforce spans languages. A lot-specific Certificate of Analysis is available for the material you receive, so your QC team can verify the lot against your own acceptance criteria, and a Technical Data Sheet is available for formulation and process review before you buy.
Why Buy from Alliance Chemical
You can buy this solvent at the scale you actually use it — the same material is offered from a 1-quart lab bottle through 5- and 55-gallon drums up to 275- and 330-gallon totes, each with SDS and lot-specific COA documentation, so a method-development lab and a coatings plant can source from one supplier. Alliance Chemical has distributed industrial chemicals since 1998 and has served more than 55,000 customers, handling regulated Class 3 freight as routine work, not an exception. The shipping and handling guidance on this page is reviewed by Andre Taki, DOT Hazmat Specialist.
