| L-Asparagine tert-butyl ester hydrochloride | L-Asparagine tert-butyl ester hydrochloride is a protected form of L-Asparagine. L-Asparagine was first isolated by Robiquet and Vauquelin from asparagus juice (a high source of L-asparagine). L-Asparagine is often incorporated into proteins, and is a basis for some cancer therapies as certain cancerous cells require L-asparagine for growth. Alternative Names: L-Asn-OtBu HCl; L-Asparagine tert-butyl ester hydrochloride; tert-Butyl L-asparaginate hydrochloride; H-Asn-OtBu HCl. Grades: ≥ 95% (HPLC). CAS No. 63094-81-5. Molecular formula: C8H16N2O3·HCl. Mole weight: 224.70. | |

| L-Aspartic acid α-methyl ester | Aspartic acid α-methyl ester is a derivative of L-Aspartic Acid, a non-essential amino acid found in food sources and dietary supplements. L-Aspartic Acid is one of the 20 proteinogenic amino acids; the building blocks of proteins. Its conjugate base L-aspartate is an excitatory neurotransmitter in the central nervous system. Alternative Names: L-Asp-OMe; H-Asp-OMe; 1-Methyl L-Aspartate; L-Aspartic Acid 1-Methyl Ester; (S)-3-Amino-4-methoxy-4-oxobutanoic acid. Grades: ≥ 99% (TLC). CAS No. 17812-32-7.
