4-Isobutylbenzenethiol CAS 4527-45-1 chemical structure

Description

CATO supplies 4-Isobutylbenzenethiol (CAS 4527-45-1), a certified reference material (molecular formula C10H14S, MW 166.28 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, an aromatic ring system, 4-Isobutylbenzenethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
