4-(tert-Butyl)-2-methylbenzenethiol CAS 15570-10-2

Description

The occurrence of 4-(tert-Butyl)-2-methylbenzenethiol is closely related to sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(tert-Butyl)-2-methylbenzenethiol (CAS 15570-10-2), molecular formula C11H16S and molecular weight 180.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H16S, 4-(tert-Butyl)-2-methylbenzenethiol contains sulfur-containing functionality, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 180.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
