L-Aspartic acid
L-Aspartic Acid (CAS 56-84-8) is a non-essential, acidic proteinogenic amino acid that Sarchem Labs supplies as a white, odorless crystalline powder for food, pharmaceutical, and biochemical research applications. Its side-chain carboxylic acid gives it a net negative charge at physiological pH, and it plays a central role in the urea cycle, nucleotide biosynthesis, and excitatory neurotransmission. Every lot ships with a COA and SDS.

Product Description

What is L-Aspartic Acid?

L-Aspartic acid is a non-essential proteinogenic amino acid carrying an acidic side-chain carboxylic acid group, giving the molecule an overall negative charge at physiological pH. It participates in biosynthesis of asparagine, arginine, lysine, methionine, and isoleucine, contributes carbon/nitrogen to purine and pyrimidine nucleotide synthesis via the urea cycle, and also functions as an excitatory neurotransmitter in the nervous system.

Uses of L-Aspartic Acid

Used as a raw material in food and dietary-supplement formulation, as a pharmaceutical synthesis intermediate, and as a standard component of cell-culture media and biochemical buffer systems. It’s also the amino-acid starting material for aspartame-related sweetener chemistry, and polyaspartic acid derivatives are researched as biodegradable industrial polymers

Safety Information

*No GHS data was located specifically for Sarchem’s SKU; L-aspartic acid as a natural amino acid generally carries a low chemical-hazard profile, but confirm against Sarchem’s own SDS.*

  • Recommended PPE: Standard laboratory precautions — gloves, safety glasses, dust control
  • Storage: Cool, dry, sealed container

FAQs: L-Aspartic acid

As a food/supplement ingredient, pharmaceutical intermediate, cell-culture media component, and precursor in sweetener and biodegradable-polymer research.

No — it's non-essential; the body can synthesize it, mainly via transamination of oxaloacetate.

56-84-8, C4H7NO4, formula weight 133.1.

It's only moderately soluble (about 4.5 g/L) — many formulations use it in dilute acid/base solution to improve solubility.

Yes, for every lot (SKU S1100), confirming the ≥98% purity spec and other listed impurity limits.
