Chemical Structure

Tert-butyl (2S,4R)-4-((methylsulfonyl)oxy)-2-((tosyloxy)methyl)pyrrolidine-1-carboxylate CAS 148017-08-7 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 Tert-butyl (2S,4R)-4-((methylsulfonyl)oxy)-2-((tosyloxy)methyl)pyrrolidine-1-carboxylate.

CATO supplies Tert-butyl (2S,4R)-4-((methylsulfonyl)oxy)-2-((tosyloxy)methyl)pyrrolidine-1-carboxylate (CAS 148017-08-7), a certified reference material (molecular formula C18H27NO8S2, MW 449.54 g/mol) for analytical method development and quality control.

Structurally, Tert-butyl (2S,4R)-4-((methylsulfonyl)oxy)-2-((tosyloxy)methyl)pyrrolidine-1-carboxylate (C18H27NO8S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 449.54 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
