Description
CATO supplies 1-Boc-2-(4-methylbenzyl)-2-pyrrolidinecarboxylic acid 351002-82-9 Boc-|A-(4-methylbenzyl)-DL-Pro-OH Boc-|A-(4-methylbenzyl)-DL-proline (CAS 351002-82-9), a certified reference material (molecular formula C18H31NO4, MW 325.44 g/mol) for analytical method development and quality control.
The molecular framework of 1-Boc-2-(4-methylbenzyl)-2-pyrrolidinecarboxylic acid 351002-82-9 Boc-|A-(4-methylbenzyl)-DL-Pro-OH Boc-|A-(4-methylbenzyl)-DL-proline (C18H31NO4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
