Trichloroacetic Acid, also known as TCA, is a monocarboxylic acid. Structurally, it is acetic acid in which all three hydrogens on the methyl group have been substituted with chlorine atoms. It is a water-soluble, colorless, crystalline solid.
Trichloroacetic Acid is used in the cosmetic industry as a chemical peel and wart remover. It is also used in biochemistry to help the precipitation of macromolecules,
As an ACS grade Reagent, Lab Alley Trichloroacetic Acid meets the toughest regulatory standards for quality and pureness.
Trichloroacetic Acid 99%, Crystals, ACS Grade is TCA, a monocarboxylic acid. Picture acetic acid with all three hydrogens on the methyl group swapped for chlorine atoms. It’s a water soluble, colorless, crystalline solid. This listing carries CAS 76-03-9, a 99.00% assay, ACS grade and a solid form. ACS grade is a reagent grade, the kind labs reach for when a method calls for a reliable, well documented material. Speaking of documents, the Product Manuals list has the Safety Data Sheet, Technical Data Sheet, Composition Breakdown, Allergen Statement, PFAS/PFOS Free Statement and TSE/BSE Declaration. Certificates of Analysis are posted by lot number.
Most buyers use TCA as a laboratory reagent in organic synthesis and to help precipitate biochemical macromolecules. The trouble starts when the paperwork doesn’t match the material, when the size you need isn’t offered, or when a supplier can’t handle hazmat. That’s where Lab Alley comes in. The SDS, Technical Data Sheet and lot COAs sit right on the product page, sizes run from 100g up to 25kg, and hazmat shipping is handled end to end. Here’s the plan. Pick your size, set up Autoship if you reorder, or send a quote request for bigger volumes. On budget, on time, every time.
