Description
As a certified reference material (CRM), 4-Isothiocyanato-3,5-dimethylphenol 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 4-Isothiocyanato-3,5-dimethylphenol (CAS 1246818-00-7), a certified reference material (molecular formula C9H9NOS, MW 179.24 g/mol) for analytical method development and quality control.
The molecular framework of 4-Isothiocyanato-3,5-dimethylphenol (C9H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
