D-aspartic acid

D-Aspartic acid (CAS 1783-96-6), commonly abbreviated as D-Asp, is the D-enantiomer of aspartic acid.

Where is D-aspartic acid used?

• Pharmaceutical and nutraceutical manufacturing: incorporated into hormone-related supplement formulations
• Biotechnology and life sciences: reference standard and biochemical reagent for receptor binding studies
• Neurological research models
• Personal care: moisture retention and pH stabilization in serums, creams, and targeted skin treatments
• Its chelating activity supports preservation systems by sequestering trace metal ions.

Good to know: Enantiomeric specificity is a critical quality parameter for these products. USP and high-purity grades are standard for procurement.

Commercial specifications

• Purity level of ≥98–99% for pharmaceutical and biotech use
• Bulk quantities for industrial formulators; smaller pack sizes for laboratory use
