Frequently Asked Questions
What is L-arginine base used for?
L-Arginine base (CAS 74-79-3) is an alpha-amino acid (C6H14N4O2) with a guanidino side chain, used as a nutritional supplement and food ingredient, as a substrate in biochemical research and pharmaceutical manufacturing, and as a JECFA-listed flavoring agent. In cosmetics it functions as an antistatic ingredient. RawSource supplies it as a bulk raw material.
What is the difference between L-arginine base and L-arginine HCl?
The base is free L-arginine (C6H14N4O2, CAS 74-79-3); the HCl form is the monohydrochloride salt (CAS 1119-34-2), which is more water-soluble and has a different mass-per-arginine and pH profile in solution. Formulators choose between them based on solubility, pH, and dosing needs; we stock both and can quote either.
Is L-arginine an amino acid?
Yes. L-Arginine is a proteinogenic alpha-amino acid distinguished by its guanidino side chain, molecular formula C6H14N4O2, CAS 74-79-3. It is supplied as a crystalline raw material with identity confirmed on the CoA.
How is L-arginine base sold in bulk?
