Frequently Asked Questions

What is Ornithine Monohydrochloride used for?

L-Ornithine Monohydrochloride (CAS 3184-13-2) is the hydrochloride salt of the non-protein amino acid L-ornithine (C5H13ClN2O2). It is used as a food flavoring ingredient and soluble amino-acid input, and as a skin-conditioning ingredient in cosmetics.

Is L-Ornithine a protein amino acid?

No. L-ornithine is a non-protein (non-proteinogenic) amino acid — it is not incorporated into proteins during translation — which distinguishes it from the standard proteinogenic amino acids. It is supplied here as the monohydrochloride salt.

Is L-Ornithine Monohydrochloride water soluble?

Yes. The hydrochloride salt is the water-soluble form of L-ornithine, making it suitable for aqueous flavoring and cosmetic formulation work.

What is the CAS number, formula, and HS code?

CAS 3184-13-2, formula C5H13ClN2O2, HS 2922.49 (amino-acids and their salts, other). Lot-specific Certificate of Analysis and SDS are available on request.

What bulk packaging and order quantities are available?

It is distributed as an amino-acid ingredient in bulk packaging for manufacturing. Submit your target volume and documentation requirements through a bulk RFQ for current pricing, pack sizes, and lead time.
