Chemical Structure
Description
As a certified reference material (CRM), (3,4-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.
CATO supplies (3,4-dimethylphenyl)methanethiol (CAS 4496-95-1), a certified reference material (molecular formula C9H12S, MW 152.26 g/mol) for analytical method development and quality control.
The molecular framework of (3,4-dimethylphenyl)methanethiol (C9H12S) is characterized by sulfur-containing functionality, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
