3-(2-Cyano-4,5-dimethoxyphenyl)-1-cyclohexylthiourea CAS 343375-03-1

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-cyclohexylthiourea.

3-(2-Cyano-4,5-dimethoxyphenyl)-1-cyclohexylthiourea (CAS 343375-03-1) is a high-purity analytical reference standard with the molecular formula C16H21N3O2S and a molecular weight of 319.42 g/mol.

The molecular framework of 3-(2-Cyano-4,5-dimethoxyphenyl)-1-cyclohexylthiourea (C16H21N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
