Chemical Structure
Description
CATO supplies 3-chloro-4-methyl-2-oxo-2H-chromen-7-yl ethyl methylphosphonate (CAS 875577-93-8), a certified reference material (molecular formula C13H14ClO5P, MW 316.67 g/mol) for analytical method development and quality control.
The molecular framework of 3-chloro-4-methyl-2-oxo-2H-chromen-7-yl ethyl methylphosphonate (C13H14ClO5P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-chloro-4-methyl-2-oxo-2H-chromen-7-yl ethyl methylphosphonate 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.
