Chemical Structure
Description
CATO supplies Dl-Asparagine Hydrate (CAS 3130-87-8), a certified reference material (molecular formula C4H8N2O3H2O, MW 150.13 g/mol) for analytical method development and quality control.
Dl-Asparagine Hydrate (C4H8N2O3H2O) contains a carbohydrate-derived structure, an amide group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
