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 1-(Tert-butylthio)cyclobutane-1-carboxylic acid.
CATO supplies 1-(Tert-butylthio)cyclobutane-1-carboxylic acid (CAS 1492778-07-0), a certified reference material (molecular formula C9H16O2S, MW 188.29 g/mol) for analytical method development and quality control.
Structurally, 1-(Tert-butylthio)cyclobutane-1-carboxylic acid (C9H16O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 188.29 g/mol, it falls into the medium-molecular-weight range.
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.
