Chemical Structure
Description
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.
CATO supplies (2S,4S)-1-(tert-Butoxycarbonyl)-4-(4-chloro-2-methylphenoxy)-2-pyrrolidinecarboxylic acid (CAS 869682-07-5), a certified reference material (molecular formula C17H22ClNO5, MW 355.81 g/mol) for analytical method development and quality control.
(2S,4S)-1-(tert-Butoxycarbonyl)-4-(4-chloro-2-methylphenoxy)-2-pyrrolidinecarboxylic acid (C17H22ClNO5) contains a flavonoid core, an amide 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.
