Full Description

L-Alanine (CAS 56-41-7) is a non-essential alpha-amino acid (C3H7NO2). It is 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.

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.
