Chemical Structure

4,4-Dimethyl-pyrrolidine-1,3-dicarboxylic acid 1-tert-butyl ester CAS 1373223-11-0 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 4,4-Dimethyl-pyrrolidine-1,3-dicarboxylic acid 1-tert-butyl ester.

4,4-Dimethyl-pyrrolidine-1,3-dicarboxylic acid 1-tert-butyl ester (CAS 1373223-11-0), molecular formula C12H21NO4 and molecular weight 243.30 g/mol, is a CATO reference standard with documented purity and traceability.

4,4-Dimethyl-pyrrolidine-1,3-dicarboxylic acid 1-tert-butyl ester (C12H21NO4) 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.
