1.2 Physical & Chemical Properties

D-Aspartic Acid (CAS 1783-96-6) is a dextrorotatory chiral amino acid with excellent water solubility. It maintains stable chemical properties under conventional storage conditions, resisting oxidation and caking.
Produced via standardized synthesis and purification processes, our products comply with USP and EP pharmacopoeia standards. Key indicators including optical purity, heavy metals, microorganisms and transmittance remain consistent across all batches.
Distinct from L-Aspartic acid in chiral structure, these two types fit different application scenarios and cannot be substituted arbitrarily. It is a dedicated basic raw material for pharmaceutical factories and food additive manufacturers worldwide.

2. Fundamental Biological Characteristics of D-Aspartic Acid

2.1 Endogenous Metabolic Traits

As a natural endogenous metabolite in the human body, D-Aspartic acid participates in physiological pathways related to the central nervous system and takes part in multiple hormone secretion processes, making it a common raw material for dietary supplement formulations.

2.2 Basic Target Profile

This substance acts as an endogenous agonist of NMDA receptors, featuring great biocompatibility and low irritation. It is widely adopted as a base ingredient for amino acid infusion and liver-supporting formulations.

3. Compliant Industrial Application Fields of D-Aspartic Acid

3.1 Pharmaceutical API & Intermediates

1. Used for synthesizing Potassium Aspartate APIs, serving as base raw materials for electrolyte-regulating preparations;
2. Liver-supporting formula material, applied in dietary supplements for ammonia metabolism regulation and fatigue relief;
3. Core component of compound amino acid infusions for nutritional injection formulations;
4. Chiral synthetic intermediate for tablets, capsules and in-vitro biochemical test reagents.

3.2 Food Additive – Raw Material for Aspartame

D-Aspartic acid is an essential synthetic raw material for the high-intensity sweetener aspartame. Aspartame breaks down into D-Aspartic acid, phenylalanine and methanol during metabolism, widely used in sugar-free beverages, meal replacements and low-sugar snacks.

3.3 Biochemical Research Standard Reagent

Laboratories, universities and biological testing institutions globally purchase D-Aspartic Acid CAS 1783-96-6 as standard samples for cell culture and human endogenous metabolism research.

6. Frequently Asked Questions for Overseas Buyers

Q1: Can D-Aspartic acid replace L-Aspartic acid and vice versa?

A: They differ in chiral configuration, physical and biological properties, leading to separate applicable scenarios. D-Aspartic Acid CAS 1783-96-6 is mainly used for pharmaceutical intermediates, liver-supporting dietary supplements and aspartame synthesis; L-Aspartic acid is mostly used for common food flavor enhancement and basic nutritional formulas. Random substitution is not allowed for custom pharmaceutical preparations.

Q2: Can pharmacopoeia-grade D-Aspartic acid be used for amino acid infusion production?

A: Our pharmacopoeia-grade D-Aspartic acid is manufactured in accordance with USP & EP standards with strict limits on microorganisms and heavy metals. It can be used as the base raw material for compound amino acid infusions, and complete COA test reports are supplied with every shipment.
