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.
(S)-2-{[(2-Chloro-acetyl)-isopropyl-amino]-methyl}-pyrrolidine-1-carboxylic acid tert-butyl ester (CAS 1353963-64-0), molecular formula C15H27ClN2O3 and molecular weight 318.84 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, (S)-2-{[(2-Chloro-acetyl)-isopropyl-amino]-methyl}-pyrrolidine-1-carboxylic acid tert-butyl ester is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
