L-asparagine monohydrate
Description
L-Asparagine monohydrate (CAS 5794-13-8) is the stable, hydrated crystalline form of the non-essential amino acid L-asparagine, used across pharmaceutical, nutritional, and cosmetic manufacturing.
It functions as a buffering agent, humectant, and stabilizer in formulations where precise pH control and moisture retention are required for the final product stability.
In pharmaceutical manufacturing, it is incorporated into parenteral nutrition solutions, amino acid infusion products, and API synthesis as a biochemical building block for various drugs.
Food and nutraceutical producers use it in amino acid-fortified supplements, functional beverages, and protein blend formulations targeting metabolic support and general wellness.
Cosmetic formulators add it to skin care preparations such as serums, moisturizers, and treatment creams where it supports moisture-binding and helps stabilize active ingredients.
It also serves as a reference standard and culture media component in biotechnology and cell biology research applications, ensuring consistent growth and metabolic performance.
L-Asparagine monohydrate is supplied as a white crystalline powder. Pharmaceutical and research-grade material is available to USP and Ph. Eur. specifications.
Food-grade supply conforming to FCC standards is also available. Bulk quantities are standard for industrial procurement, with smaller pack sizes for laboratory use.
