Chemical Structure
Description
CATO supplies 2-(Methylthio)spiro[3.4]octane-2-carboxylic acid (CAS 1490578-35-2), a certified reference material (molecular formula C10H16O2S, MW 200.30 g/mol) for analytical method development and quality control.
The molecular framework of 2-(Methylthio)spiro[3.4]octane-2-carboxylic acid (C10H16O2S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
