Chemical Structure
Description
The molecular framework of tert-butyl (4S)-4-(methoxymethyl)-2,2-dioxo-oxathiazolidine-3-carboxylate (C9H17NO6S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
tert-butyl (4S)-4-(methoxymethyl)-2,2-dioxo-oxathiazolidine-3-carboxylate (CAS 2023006-41-7) is a high-purity analytical reference standard with the molecular formula C9H17NO6S and a molecular weight of 267.30 g/mol.
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.
