Frequently Asked Questions

What is L-Aspartic Acid used for?

L-Aspartic Acid (CAS 56-84-8) is a non-essential dicarboxylic alpha-amino acid (C4H7NO4) used as a raw material in the manufacture of the sweetener aspartame and of peptide pharmaceuticals, as a nutritional supplement and food flavoring agent, in culture-media preparation, and as a chelating/metal-complexing agent. RawSource supplies FCC-grade material in bulk.

Is L-aspartic acid an acid?

Yes. It is a dicarboxylic amino acid bearing two carboxyl groups plus an amino group (C4H7NO4, CAS 56-84-8), giving it an acidic character in solution. This is also what makes it useful as a chelating/metal-complexing agent and an aspartame feedstock.

What grade is RawSource L-Aspartic Acid?

This material is offered to FCC (Food Chemicals Codex) specification, which defines identity, assay, and purity limits for food-grade use. Each lot ships with a Certificate of Analysis documenting conformance and an SDS. Contact us to confirm the current specification for your application.

How is L-Aspartic Acid sold in bulk and what does it cost?

It is supplied as a crystalline powder in industrial packaging (bags, drums) sized for food, supplement, and synthesis use. Pricing depends on grade and order volume, so we quote per request rather than list a fixed price; contact us for bulk pack sizes, MOQ, lead time, and a current quote. CoA and SDS are provided with every shipment.

What is the CAS number and HS code for L-Aspartic Acid?

It is CAS 56-84-8 with molecular formula C4H7NO4. As an amino acid it is classified under HS subheading 2922.49. Full identity and specification data accompany each order on the CoA.
