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 (3Z)-3-{[(2,5-dichlorophenyl)amino]methylidene}-1,3-dihydro-2-benzothiophen-1-one.
(3Z)-3-{[(2,5-dichlorophenyl)amino]methylidene}-1,3-dihydro-2-benzothiophen-1-one (CAS 339114-99-7), molecular formula C15H9Cl2NOS and molecular weight 322.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3Z)-3-{[(2,5-dichlorophenyl)amino]methylidene}-1,3-dihydro-2-benzothiophen-1-one (C15H9Cl2NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 (3Z)-3-{[(2,5-dichlorophenyl)amino]methylidene}-1,3-dihydro-2-benzothiophen-1-one 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.
