(S)-1-(tert-Butoxycarbonyl)-2-methyl-5-oxopyrrolidine-2-carboxylic acid CAS 1932233-78-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-1-(tert-Butoxycarbonyl)-2-methyl-5-oxopyrrolidine-2-carboxylic acid.

CATO supplies (S)-1-(tert-Butoxycarbonyl)-2-methyl-5-oxopyrrolidine-2-carboxylic acid (CAS 1932233-78-7), a certified reference material (molecular formula C11H17NO5, MW 243.26 g/mol) for analytical method development and quality control.

(S)-1-(tert-Butoxycarbonyl)-2-methyl-5-oxopyrrolidine-2-carboxylic acid (C11H17NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), (S)-1-(tert-Butoxycarbonyl)-2-methyl-5-oxopyrrolidine-2-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
