Chemical Structure

4-(Isobutylthio)benzenethiol CAS 56056-59-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 198.35 g/mol gives 4-(Isobutylthio)benzenethiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(Isobutylthio)benzenethiol (CAS 56056-59-8), a certified reference material (molecular formula C10H14S2, MW 198.35 g/mol) for analytical method development and quality control.

4-(Isobutylthio)benzenethiol (C10H14S2) contains sulfur-containing functionality, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
