Chemical Structure

o-Toluenethiol CAS 137-06-4 chemical structure

Description

As a certified reference material (CRM), o-Toluenethiol 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.

CATO supplies o-Toluenethiol (CAS 137-06-4), a certified reference material (molecular formula C7H8S, MW 124.20 g/mol) for analytical method development and quality control.

Structurally, o-Toluenethiol (C7H8S) contains sulfur-containing functionality, 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 124.20 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
