Frequently Asked Questions
What is L-Alanine used for?
L-Alanine (CAS 56-41-7) is a non-essential alpha-amino acid (C3H7NO2) used as a nutritional supplement and food flavoring agent, as a substrate in microbiological and biochemical research and culture media, and as an intermediate in organic synthesis. It also functions as a chelating agent and as an antistatic ingredient in cosmetics. RawSource supplies USP-grade L-alanine in bulk.
What is the difference between L-alanine and beta-alanine?
They are structural isomers with different chemistry: L-alanine is the alpha-amino acid (amino group on the alpha carbon, C3H7NO2, CAS 56-41-7), while beta-alanine carries the amino group on the beta carbon and is a separate compound. They are sourced and specified independently; we can quote either against your spec.
What grade is RawSource L-Alanine?
This material is offered to USP (United States Pharmacopeia) specification, which defines identity, assay, and impurity limits. Each lot ships with a Certificate of Analysis documenting conformance, plus an SDS. Contact us to confirm the current specification for your application.
How is L-Alanine sold in bulk?
It is supplied as a crystalline powder in industrial packaging (bags, drums) sized for food, supplement, and synthesis use. Contact us for bulk pack sizes, minimum order quantity, lead time, and a current quote. CoA and SDS are provided with every shipment.
What is the CAS number and HS code for L-Alanine?
L-Alanine is CAS 56-41-7 with molecular formula C3H7NO2. As an amino acid it is classified under HS subheading 2922.49. Full identity and specification data accompany each order on the CoA.
What is the REACH and TSCA regulatory status of L-Alanine (Alanine)?
L-Alanine (Alanine) (CAS 56-41-7) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 200-273-8).
