Chemical Structure

(S)-tert-Butyl 3-(5-bromothiophene-2-sulfonamido)pyrrolidine-1-carboxylate CAS 1261234-18-7 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)-tert-Butyl 3-(5-bromothiophene-2-sulfonamido)pyrrolidine-1-carboxylate.

CATO supplies (S)-tert-Butyl 3-(5-bromothiophene-2-sulfonamido)pyrrolidine-1-carboxylate (CAS 1261234-18-7), a certified reference material (molecular formula C13H19BrN2O4S2, MW 411.33 g/mol) for analytical method development and quality control.

Structurally, (S)-tert-Butyl 3-(5-bromothiophene-2-sulfonamido)pyrrolidine-1-carboxylate (C13H19BrN2O4S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 411.33 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
