3-(2-Cyano-4,5-dimethoxyphenyl)-1-(3,5-dimethylphenyl)thiourea CAS 343374-96-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Cyano-4,5-dimethoxyphenyl)-1-(3,5-dimethylphenyl)thiourea.

CATO supplies 3-(2-Cyano-4,5-dimethoxyphenyl)-1-(3,5-dimethylphenyl)thiourea (CAS 343374-96-9), a certified reference material (molecular formula C18H19N3O2S, MW 341.43 g/mol) for analytical method development and quality control.

The molecular framework of 3-(2-Cyano-4,5-dimethoxyphenyl)-1-(3,5-dimethylphenyl)thiourea (C18H19N3O2S) is characterized by a steroid core, an amide group, a sulfone group, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 3-(2-Cyano-4,5-dimethoxyphenyl)-1-(3,5-dimethylphenyl)thiourea 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.
