[(Z)-({1-[4-(trifluoromethoxy)phenyl]-1H-pyrrol-2-yl}methylidene)amino]thiourea CAS 551921-76-7 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 [(Z)-({1-[4-(trifluoromethoxy)phenyl]-1H-pyrrol-2-yl}methylidene)amino]thiourea.

[(Z)-({1-[4-(trifluoromethoxy)phenyl]-1H-pyrrol-2-yl}methylidene)amino]thiourea (CAS 551921-76-7), molecular formula C13H11F3N4OS and molecular weight 328.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [(Z)-({1-[4-(trifluoromethoxy)phenyl]-1H-pyrrol-2-yl}methylidene)amino]thiourea (C13H11F3N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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).

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.

CATO manufactures [(Z)-({1-[4-(trifluoromethoxy)phenyl]-1H-pyrrol-2-yl}methylidene)amino]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.
