Description

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.

2-Methyl-5-(trifluoromethyl)benzenethiol (CAS 1429056-31-4) is a high-purity analytical reference standard with the molecular formula C8H7F3S and a molecular weight of 192.20 g/mol.

Structurally, 2-Methyl-5-(trifluoromethyl)benzenethiol (C8H7F3S) contains sulfur-containing functionality, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 192.20 g/mol, it falls into the medium-molecular-weight range. 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).

As a certified reference material (CRM), 2-Methyl-5-(trifluoromethyl)benzenethiol 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.
