Product Overview
75% Vinegar ACS Grade is a concentrated aqueous acetic acid solution (C2H4O2, CAS 64-19-7) carrying the ACS Grade designation. At 75% acetic acid, it is far stronger than household vinegar and is handled as a corrosive industrial chemical, not a kitchen product. The typical buyer is a laboratory sourcing an acetic acid solution specified by grade descriptor, a water-treatment operator dosing for pH control, or a plant running descaling and cleaning work that needs high-concentration acid with paperwork behind it.
It is a clear colorless liquid with a pungent vinegar odor, offered from 1 quart bottles for bench work up to 55 gal drums and 275–330 gal totes for production use. Every order includes a Safety Data Sheet, and a lot-specific Certificate of Analysis is available for buyers who need documented lot data before use.
Why This Concentration
Pick 75% when your process needs maximum acetic acid strength per gallon delivered. Higher concentration means less water hauled and stored, smaller dose volumes for the same acid demand, and less dilution work on your end when your procedure calls for strong acid. The trade-off is handling: this solution carries the GHS signal word Danger and causes severe skin burns and eye damage on contact (per the product's GHS classification), and it ships as a regulated Class 8 corrosive. Your team needs compatible containers, acid-rated PPE, and a real transfer procedure.
If your application only needs moderate acidity — routine cleaning, weed control, light descaling — a lower strength is easier to handle and often cheaper per job. Compare 50% Vinegar for strong cleaning work, 30% Vinegar for general industrial use, or 10% Vinegar for mild-duty applications. For work at this strength that does not call for the ACS Grade designation or a COA, see our standard 75% Vinegar.
Chemical Profile
This product is a clear colorless liquid — a 75% aqueous solution of acetic acid — with the pungent vinegar odor characteristic of concentrated acetic acid. Its density is 1.069 g/mL at 20 °C, noticeably heavier than water, which matters when calculating drum weights and pump sizing. The solution is fully miscible in practice, with published solubility of 100 mg/mL or greater at 73 °F. Vapor pressure runs 11.4 mmHg at 68 °F, rising to 20 mmHg at 86 °F, so vapor concentration in a closed, warm storage room climbs quickly — plan ventilation accordingly. The acetic acid molecule itself is C2H4O2 with a molecular weight of 60.05, CAS 64-19-7. These are our published product data for this listing; the lot-specific values ship on the COA.
Industrial Applications
Concentrated acetic acid earns its place across water treatment, laboratory, and industrial cleaning work:
-
pH adjustment and pH control (water treatment). Operators dose acetic acid solution to pull pH down in treatment trains and process water. The 75% strength cuts the dose volume needed per unit of acid demand compared with dilute grades.
-
Chemical reagent (manufacturing and synthesis). Acetic acid is a workhorse reagent in organic synthesis, serving as a feedstock and reactant in producing esters, acetates, and other organic compounds.
-
Solvent in organic chemistry (laboratory). Research and QC laboratories use acetic acid as a solvent and medium in organic synthesis and extraction procedures, where the ACS Grade descriptor is commonly written into purchasing specs.
-
Industrial cleaning and descaling. Acetic acid attacks mineral scale and deposits. Maintenance crews dilute concentrated stock to the working strength their procedure calls for, keeping one high-strength drum instead of pallets of dilute product.
Verify material compatibility before use in any of these processes — concentrated acetic acid is corrosive to many metals and some elastomers.
Handling & Storage
Treat this product as the corrosive it is. The GHS signal word is Danger, with hazard statement H314 — causes severe skin burns and eye damage (per the product's GHS classification). Acid-resistant gloves, splash goggles or a face shield, and chemical-resistant clothing are the baseline PPE for transfers. Work with ventilation; the vapor is pungent and pressure rises with temperature.
Store cool, dry, and out of direct sunlight in HDPE or glass containers — the same packaging families we ship it in. Keep it segregated from strong oxidizers and bases. Keep containers closed and labeled, and stage secondary containment sized to your largest container. Our warehouse team handles this product in quart-to-tote quantities daily, and the same rules apply at any scale: slow transfers, compatible fittings, and an eyewash within reach.
Hazmat & Shipping
This solution ships as fully regulated hazmat. It is assigned UN2790 (per 49 CFR 172.101), Hazard Class 8 — corrosive (per 49 CFR 172.101), Packing Group II (per 49 CFR 172.101), under the proper shipping name "Acetic acid solution, with not less than 50 percent but not more than 80 percent acid, by mass" (per 49 CFR 172.101). Every container leaves our dock packaged, marked, and labeled to those requirements. Receivers should be prepared to accept a Class 8 corrosive shipment under their own site procedures.
Documentation
An SDS ships with every order and is available in English, Spanish, French, and Japanese. A Technical Data Sheet is available for spec review before purchase, and a lot-specific Certificate of Analysis is available so your QC team can review the tested values for the exact lot you receive. If your quality system requires documentation on file before first use, request the TDS and a sample COA with your quote.
