Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N'-(2,3-dichlorobenzoyl)-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide.
N'-(2,3-dichlorobenzoyl)-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (CAS 478062-69-0), molecular formula C16H11Cl2N3O2S and molecular weight 380.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N'-(2,3-dichlorobenzoyl)-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (C16H11Cl2N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 N'-(2,3-dichlorobenzoyl)-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide 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.
