Frequently Asked Questions
What is L-Cysteine HCl Monohydrate used for?
It is the monohydrate hydrochloride salt of the sulfur-containing amino acid L-cysteine. Industrially it functions as a reducing agent and dough conditioner/strengthener in baking, as a food flavoring ingredient, as a soluble amino-acid input for nutritional formulations, and as a reducing and hair-conditioning ingredient in cosmetics.
Is L-Cysteine HCl Monohydrate water soluble?
Yes. The hydrochloride monohydrate salt is the freely water-soluble form of L-cysteine, which makes it the preferred grade where rapid dissolution into aqueous or dough systems is required versus the free base.
What is the CAS number and molecular formula?
CAS 56-91-7. It is supplied to FCC (Food Chemicals Codex) specification with Kosher certification. Lot-specific Certificate of Analysis and SDS documentation are available on request.
What is the HS code for L-Cysteine HCl Monohydrate?
It classifies under HS 2930.90 — organo-sulfur compounds, other. Confirm the final import classification with your customs broker for the destination country.
