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 Methyl (Z)-2-(2,6-dichloroisonicotinoyl)-3-(methylamino)but-2-enoate.
Methyl (Z)-2-(2,6-dichloroisonicotinoyl)-3-(methylamino)but-2-enoate (CAS 82140-55-4), molecular formula C12H12Cl2N2O3 and molecular weight 303.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl (Z)-2-(2,6-dichloroisonicotinoyl)-3-(methylamino)but-2-enoate (C12H12Cl2N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. 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 Methyl (Z)-2-(2,6-dichloroisonicotinoyl)-3-(methylamino)but-2-enoate 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.
