s-(tert-Butylthio)-l-cysteine hydrate CAS 313223-16-4

Description

The occurrence of s-(tert-Butylthio)-l-cysteine hydrate is closely related to an amide group, 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.

CATO supplies s-(tert-Butylthio)-l-cysteine hydrate (CAS 313223-16-4), a certified reference material (molecular formula C7H15NO2S2H2O, MW 227.34 g/mol) for analytical method development and quality control.

Structurally, s-(tert-Butylthio)-l-cysteine hydrate (C7H15NO2S2H2O) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 227.34 g/mol, it falls into the medium-molecular-weight range. 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.

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.
