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 3-Chloro-6-(thiophen-3-yl)pyridazine.
3-Chloro-6-(thiophen-3-yl)pyridazine (CAS 78784-79-9) is a high-purity analytical reference standard with the molecular formula C8H5ClN2S and a molecular weight of 196.66 g/mol.
The molecular framework of 3-Chloro-6-(thiophen-3-yl)pyridazine (C8H5ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 3-Chloro-6-(thiophen-3-yl)pyridazine 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.
