Chemical Structure
Description
Methyl (E)-2-(2-chlorobenzylidene)hydrazine-1-carboxylate (CAS 200280-89-3) is a high-purity analytical reference standard with the molecular formula C9H9ClN2O2 and a molecular weight of 212.63 g/mol.
Methyl (E)-2-(2-chlorobenzylidene)hydrazine-1-carboxylate (C9H9ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Methyl (E)-2-(2-chlorobenzylidene)hydrazine-1-carboxylate 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.
