Chemical Structure

Tert-butyl methanesulfonate CAS 16427-41-1 chemical structure

Description

The occurrence of Tert-butyl methanesulfonate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Tert-butyl methanesulfonate (CAS 16427-41-1), molecular formula C5H12O3S and molecular weight 152.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Tert-butyl methanesulfonate (C5H12O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
