Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(E)-3-(4-chlorophenyl)-3-oxopropanal O-methyl oxime (CAS 339021-13-5), molecular formula C10H10ClNO2 and molecular weight 211.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-3-(4-chlorophenyl)-3-oxopropanal O-methyl oxime (C10H10ClNO2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (E)-3-(4-chlorophenyl)-3-oxopropanal O-methyl oxime meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
