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 (2Z)-2-chloro-2-[2-(2,3-dimethylphenyl)hydrazin-1-ylidene]acetate (CAS 37522-18-2) is a high-purity analytical reference standard with the molecular formula C12H15ClN2O2 and a molecular weight of 254.71 g/mol.
The molecular framework of Ethyl (2Z)-2-chloro-2-[2-(2,3-dimethylphenyl)hydrazin-1-ylidene]acetate (C12H15ClN2O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Ethyl (2Z)-2-chloro-2-[2-(2,3-dimethylphenyl)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.
