Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N'-(4-Bromobenzylidene)-2-(4-chloro-2-methylphenoxy)acetohydrazide (CAS 329049-30-1), molecular formula C16H14BrClN2O2 and molecular weight 381.65 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H14BrClN2O2, N'-(4-Bromobenzylidene)-2-(4-chloro-2-methylphenoxy)acetohydrazide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 381.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures N'-(4-Bromobenzylidene)-2-(4-chloro-2-methylphenoxy)acetohydrazide 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.
