Chemical Structure
Description
5-(2-(2-Chlorobenzoyl)hydrazinyl)-5-oxopentanoic acid (CAS 333405-85-9) is a high-purity analytical reference standard with the molecular formula C12H13ClN2O4 and a molecular weight of 284.70 g/mol.
The molecular framework of 5-(2-(2-Chlorobenzoyl)hydrazinyl)-5-oxopentanoic acid (C12H13ClN2O4) 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 the protonation state of its nitrogen-containing groups, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
