Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (E)-2-(4-chlorophenyl)-1-(2,4-dihydroxyphenyl)ethan-1-one oxime (CAS 890635-25-3), a certified reference material (molecular formula C14H12ClNO3, MW 277.70 g/mol) for analytical method development and quality control.
The molecular framework of (E)-2-(4-chlorophenyl)-1-(2,4-dihydroxyphenyl)ethan-1-one oxime (C14H12ClNO3) 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)-2-(4-chlorophenyl)-1-(2,4-dihydroxyphenyl)ethan-1-one 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.
