Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 159.99 g/mol gives H-β-Chloro-DL-Ala-OH · HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
H-β-Chloro-DL-Ala-OH · HCl (CAS 35401-46-8), molecular formula C3H6ClNO2HCl and molecular weight 159.99 g/mol, is a CATO reference standard with documented purity and traceability.
H-β-Chloro-DL-Ala-OH · HCl (C3H6ClNO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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.
