(3,5-Dimethylphenyl)methanethiol CAS 75155-96-3

Description

The occurrence of (3,5-Dimethylphenyl)methanethiol is closely related to sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3,5-Dimethylphenyl)methanethiol (CAS 75155-96-3), molecular formula C9H12S and molecular weight 152.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, an aromatic ring system, (3,5-Dimethylphenyl)methanethiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.26 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.

As a certified reference material (CRM), (3,5-Dimethylphenyl)methanethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
