Description

D-Aspartic acid (CAS 1783-96-6 ), commonly abbreviated as D-Asp, is the D-enantiomer of aspartic acid used across pharmaceutical, biotechnology, and personal care applications. It functions as a chelating agent, pH buffer, and humectant depending on the formulation context. In pharmaceutical and nutraceutical manufacturing, D-Asp is incorporated into hormone-related supplement formulations. Enantiomeric specificity is a critical quality parameter for these products. Biotechnology and life sciences suppliers source it as a reference standard and biochemical reagent for receptor binding studies. It is also utilized in neurological research models. In personal care formulations, it contributes moisture retention and pH stabilization in serums, creams, and targeted skin treatments. Its chelating activity also supports preservation systems by sequestering trace metal ions that would otherwise degrade active ingredients. This ensures the long-term stability of complex chemical mixtures. D-Aspartic acid is available as a white crystalline powder in research-grade and pharmaceutical-grade specifications. USP and high-purity grades are standard for procurement. These grades typically maintain a purity level of ≥98–99% for pharmaceutical and biotech use. Bulk quantities are offered for industrial formulators, with smaller pack sizes available for laboratory use. Quality control teams rely on these high standards for consistent results. Our supply chain ensures that all materials meet the rigorous demands of modern chemical and biological manufacturing processes. Contact us for supply of D-aspartic acid Request Quote
