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 (2E)-3-(4-Bromophenyl)-2-[2-(4-chlorophenyl)hydrazin-1-ylidene]-3-oxopropanal.
(2E)-3-(4-Bromophenyl)-2-[2-(4-chlorophenyl)hydrazin-1-ylidene]-3-oxopropanal (CAS 338414-04-3), molecular formula C15H10BrClN2O2 and molecular weight 365.61 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-3-(4-Bromophenyl)-2-[2-(4-chlorophenyl)hydrazin-1-ylidene]-3-oxopropanal (C15H10BrClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 (2E)-3-(4-Bromophenyl)-2-[2-(4-chlorophenyl)hydrazin-1-ylidene]-3-oxopropanal 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.
