Product Description
L-Arginine L-Aspartate is a compound comprising the amino acid L-arginine and L-aspartic acid in a 1:1 ratio. Also referred to as Arginine Aspartate, it is identified by CAS No. 7675-83-4 and has a molecular formula of C10H21N5O6 with a molecular weight of approximately 307.30 g/mol.
This amino acid compound is generally described as a white to off-white solid or powder. Its strong affinity for water is an important consideration when evaluating it for aqueous preparation or formulation work. The material is also reported to be hygroscopic, so moisture exposure and packaging conditions can influence its handling and storage requirements.
L-Arginine L-Aspartate is listed in chemical and ingredient references for pharmaceutical-related research and selected personal care applications, including skin-conditioning and hair-conditioning functions. The suitability of any particular grade depends on its purity, impurity profile, analytical documentation, and the requirements of the intended application. Its inclusion in ingredient references should not be interpreted as approval for a specific therapeutic or consumer use.
For procurement, buyers should confirm that the material contains the intended L-isomers and matches CAS No. 7675-83-4. The specification should also clarify assay, moisture or loss on drying, appearance, solubility, packaging, and storage requirements. Where the ingredient is intended for regulated applications, the supplier should provide documentation appropriate to the required grade and destination market.

FAQ
Q1: What is L-Arginine L-Aspartate?
L-Arginine L-Aspartate is a compound of L-arginine and L-aspartic acid in a 1:1 ratio. It is also commonly called Arginine Aspartate.
Q2: What is the CAS number of L-Arginine L-Aspartate?
The CAS number is 7675-83-4. Buyers should confirm this identifier on the product label and accompanying documentation.
Q3: What are the molecular formula and molecular weight of L-Arginine L-Aspartate?
Its molecular formula is C10H21N5O6, and its molecular weight is approximately 307.30 g/mol.
Q4: Is L-Arginine L-Aspartate soluble in water?
Published supplier references describe it as very soluble in water. Actual dissolution behavior can depend on the grade, temperature, concentration, and preparation conditions.
Q5: Is L-Arginine L-Aspartate hygroscopic?
Yes. It is reported to be hygroscopic, meaning it can absorb moisture from its surroundings. Moisture protection and appropriate packaging are therefore important during storage and handling.
Q6: What is the difference between L-Arginine and L-Arginine L-Aspartate?
L-Arginine is an individual amino acid, while L-Arginine L-Aspartate contains both L-arginine and L-aspartic acid in a 1:1 composition. They have different chemical identities and molecular weights and should not be treated as interchangeable.
Q7: What applications is L-Arginine L-Aspartate used for?
Published ingredient references include pharmaceutical-related research and selected personal care applications, including skin-conditioning and hair-conditioning functions. The suitability of the material depends on its grade and the requirements of the intended application.
Q8: What should buyers check before ordering L-Arginine L-Aspartate?
Confirm CAS number, composition, assay, moisture specification, appearance, packaging, and batch documentation. For regulated applications, verify the required grade, quality documentation, and compliance requirements for the destination market.
Q9: How should L-Arginine L-Aspartate be stored?
Because the material is reported to be hygroscopic, it should be kept in a tightly closed container and protected from excess moisture. Follow the supplier’s current technical data sheet and safety data sheet for the specified storage conditions.
Q10: Are Targifor and Sargenor interchangeable with every L-Arginine L-Aspartate raw material?
No. These names are associated with commercial products or brands in public references. A brand name alone does not establish that a raw material has the same grade, formulation, or regulatory status. Confirm the exact product identity and documentation before making comparisons.
