The solubility specified here was measured in water. The solubility is influenced by many factors in the application.
Sodium L-Aspartate is the sodium salt of L-aspartic acid. It is supplied as a crystalline, readily water-soluble powder. Its defined composition and high solubility make it particularly suitable for aqueous formulations, cell culture media and biotechnological processes.
The actual solubility in an application may be influenced by concentration, temperature, pH and other formulation components.
Dr. Paul Lohmann® supplies Sodium L-Aspartate for specialized B2B applications, particularly in the biopharmaceutical and biotechnology industries.
In the biopharmaceutical industry, Sodium L-Aspartate DPL-BioPharm grade is used as an amino acid component in cell culture media and upstream bioprocessing. Aspartic acid is an important building block in cell metabolism and supports the growth and functionality of cultured cells.
The sodium salt offers significantly improved water solubility compared with poorly soluble amino acid forms. This facilitates the preparation of concentrated stock solutions and defined culture media used in biopharmaceutical production.
Typical applications include:
The appropriate concentration depends on the cell line, microorganism, production system and desired process conditions. Careful formulation of the culture medium is therefore essential for reproducible cell growth and production performance.
Sodium L-Aspartate can serve as a defined source of L-aspartate in media for mammalian cells, microorganisms and other biological expression systems. Its high water solubility supports homogeneous distribution within the culture medium and can simplify the preparation of liquid concentrates.
In fermentation and cell culture processes, amino acids are used as nutrients and metabolic building blocks. Their precise concentration can influence cell growth, productivity and the formation of the desired biological product.
Sodium L-Aspartate in bioprocess applications:
Process suitability and concentration should always be confirmed for the individual cell line and manufacturing process.
In addition to biopharmaceutical applications, chemically pure Sodium L-Aspartate can be evaluated as a defined amino acid salt for laboratory, research and specialty chemical formulations.
Its high solubility and specified chemical composition are advantageous when reproducible aqueous solutions are required. It may also be used as a raw material in the development of amino acid derivatives or specialized chemical formulations.
Possible applications include:
The suitability of Sodium L-Aspartate for a specific formulation or process must be evaluated by the customer under the intended application conditions.
Choosing the right Sodium L-Aspartate manufacturer and supplier is essential for industries requiring consistent raw material quality, comprehensive documentation and secure supply chains.
As an established global supplier of specialty salts, Dr. Paul Lohmann® offers:
The DPL-BioPharm quality concept is designed to meet the specific requirements of biopharmaceutical production, including controlled microbiological quality, endotoxin levels and heavy metal profiles according to the relevant product specification.
We operate under internationally recognized quality and safety standards.
Quality assurance includes:
These measures ensure that Sodium L-Aspartate meets the high expectations of customers in biopharmaceutical, biotechnology and specialty chemical applications. The availability of specific certificates and analytical parameters should be confirmed for the selected product grade.
