Description

L(+)-Asparagine Monohydrate is the naturally occurring L-enantiomer of the amino acid asparagine, supplied as a monohydrate crystalline powder. This high-purity chiral building block is essential for biochemical research, pharmaceutical synthesis, and specialized nutrition applications where stereochemical integrity is critical. It serves as a key intermediate for peptide synthesis and is vital for cell culture media formulations in biotechnology, pharmaceutical development, and diagnostic manufacturing.

Application

• Pharmaceutical Intermediate: A crucial chiral precursor in the synthesis of peptides, APIs (Active Pharmaceutical Ingredients), and other bioactive compounds.
• Biochemical Research & Cell Culture: A fundamental component of cell culture media, microbiological media, and as a standard in amino acid analysis and metabolic studies.
• Nutritional Science: Used in research on specialized enteral/parenteral nutrition and the development of amino acid supplements.
• Food Science: Employed as a reference standard and in research related to flavor precursors (e.g., acrylamide formation) and food chemistry.
• Cosmetic & Personal Care: Investigated for use in advanced skincare formulations for its potential moisturizing and skin-conditioning properties.

Quality Control

Our L(+)-Asparagine Monohydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for research and industrial applications. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, optical rotation, and impurity profiles. While typically produced to meet general reagent or biochemical grade specifications, production can be aligned with relevant pharmacopeial guidelines (USP/EP) upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can affect weight and stability.
