(2S,3S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-3-methylpyrrolidine-2-carboxylic acid CAS 1367552-70-2 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 (2S,3S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-3-methylpyrrolidine-2-carboxylic acid.

(2S,3S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-3-methylpyrrolidine-2-carboxylic acid (CAS 1367552-70-2) is a high-purity analytical reference standard with the molecular formula C11H19NO5 and a molecular weight of 245.27 g/mol.

(2S,3S,4R)-1-(tert-butoxycarbonyl)-4-hydroxy-3-methylpyrrolidine-2-carboxylic acid (C11H19NO5) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

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.
