Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (5-Fluoro-2-methylphenyl)thiourea.
(5-Fluoro-2-methylphenyl)thiourea (CAS 16822-86-9) is a high-purity analytical reference standard with the molecular formula C8H9FN2S and a molecular weight of 184.23 g/mol.
The molecular framework of (5-Fluoro-2-methylphenyl)thiourea (C8H9FN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. 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.
CATO manufactures (5-Fluoro-2-methylphenyl)thiourea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
