Hydrochloric Acid 37% Solution, ACS Reagent Grade is is certified as the American Chemical Society (ACS) reagent due to its high level of purity and is acceptable for use in analytical applications and research laboratories. The 37% solution is the maximum attainable concentration of hydrogen chloride gas in water.
Hydrochloric Acid 37% Solution, ACS Reagent Grade is hydrogen chloride gas dissolved in water, sold here as a liquid under CAS 7647-01-0. The assay runs from 36.0% to 38.0%, and the grade is ACS, which means it’s certified as an American Chemical Society reagent for its high level of purity. That makes it a fit for analytical applications and research laboratories. The page lists documents you can open before you buy, including the Safety Data Sheet, Technical Data Sheet, Allergen Statement, BPA Statement, Non-Irradiation Statement, PFAS/PFOS Free Statement and TSE/BSE Declaration, along with a list of Certificates of Analysis. Lab Alley sells it in sizes from 500ml up to 55 gallons, plus case packs.
You’ll find this acid in batteries, as a lab reagent, as a descaling agent and as a reducing agent. Wherever you use it, a few things can trip you up. Impurities can throw off your results. Missing paperwork can stall a purchase. Some suppliers can’t ship hazmat in the size you need. Lab Alley fixes that. The Safety Data Sheet, Technical Data Sheet and Certificates of Analysis sit on this page, sizes run from small bottles to bulk, and we handle the hazmat side of shipping. Your plan is simple. Choose a size, set up Autoship if you reorder, or request a quote for larger volumes. We deliver on budget, on time, every time.
