Chemical Structure
Description
CATO supplies Phenyl-d5 Isothiocyanate (CAS 74881-77-9), a certified reference material (molecular formula C7D5NS, MW 140.22 g/mol) for analytical method development and quality control.
Phenyl-d5 Isothiocyanate (C7D5NS) contains deuterium isotope labeling, a nitrile group, sulfur-containing functionality, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Phenyl-d5 Isothiocyanate 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.
