The L-Aspartic Acid (CAS 56-84-8) 98.5% - 101.5% Dried Basis is an amino acid with a high degree of purity and is commonly used as a biochemical researcher, pharmaceutical procuder or other advanced laboratory applications. The original specification comes with analytical standards, so the material has a consistent and stable composition and will perform reliably in sensitive formulations.
In general, this is not just a plain old amino acid powder - it is a precise, controlled product that is used for applications where mixture consistency is very important. If you work in the laboratory or an R&D facility, you likely already know that even small differences in the purity of this material can lead to vastly different results; this is why this product is the preferred grade for such applications.

What does "Dried Basis 98.5–101.5%" actually mean?
This is an often-asked question by our customers.
Simply put, when a product is tested for purity, the moisture content is removed. Thus, the purity of the product is based solely on the material when dry. The "% d.b." after the number indicates a range of purity results that indicate compliance with analystical tolerances typically used in the pharmaceutical and biochemistry industries, 98.5%–101.5%.
So what can you conclude from this?
- The product will be produced under highly controlled conditions.
- The quality of the product will remain consistent from different batches.
- The product will be suitable for precise formulation processes.
Advantages for Use
Why do many labs/manufacturers prefer to use this type of amino acid?
- The purity is stable and consistent with each batch.
- The product will perform well in sensitive biochemical environments.
- The product can be relied upon for batch-to-batch quality control.
- The product exhibits good solubility for use in formulations.
- The product has been tested using stringent analytical methods compliant with industry standards.
The key to successfully producing or using dry basis amino acids in real-world applications is to ensure batch-to-batch consistency. If there are differences between two batches, it can affect the results of an experiment or production line. Therefore, amino acids that have a controlled grade, such as this one, are widely used in laboratory and manufacturing operations.
Use Areas
L-aspartic acid 98.5% to 101.5% has applications in many areas such as:
- Synthesis of pharmaceutical intermediates;
- Biochemical and cell/culture research;
- Amino acid and nutritional formulation studies;
- Ingredient development for cosmetics;
- Chemical laboratory reagent systems.
In research labs, L-aspartic acid is often added to amino acid mixtures for controlled metabolic studies. In formulation development, it is used to maintain balanced amino acid composition.
Have you ever considered why some formulations have more predictable behavior than others? Many times it's the quality and specification of the amino acids that have been used.

Final Thoughts
L-Aspartic Acid 98.5–101.5% (Dried Basis) provides both a physical/chemical composition as well as dependability. Dependability is usually much more valuable when measured in reliability of continued use for the same purpose. This is why the L-Aspartic Acid specification is one of the most commonly used specifications for both laboratories and production facilities that require an accurate level of measurement.
If you require a reliable grade of amino acid for research and development (or formulation) of products, this product will meet your needs.
