Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 171.19 g/mol gives DL-Aspartic acid potassium salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies DL-Aspartic acid potassium salt (CAS 14434-35-6), a certified reference material (molecular formula C4H6NO4K, MW 171.19 g/mol) for analytical method development and quality control.
DL-Aspartic acid potassium salt (C4H6NO4K) 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.
