Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl-2-chloro-2-[2-(3-chlorophenyl)hydrazin-1-ylidene]acetate (CAS 35229-83-5), molecular formula C10H10Cl2N2O2 and molecular weight 261.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl-2-chloro-2-[2-(3-chlorophenyl)hydrazin-1-ylidene]acetate (C10H10Cl2N2O2) 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 its high hydrophobicity (logP), 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).
CATO manufactures Ethyl-2-chloro-2-[2-(3-chlorophenyl)hydrazin-1-ylidene]acetate 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.
