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 Methyl (4-nitrophenyl) hydrogen phosphate (CAS 15930-83-3), a certified reference material (molecular formula C7H7NO6P, MW 232.11 g/mol) for analytical method development and quality control.
The molecular framework of Methyl (4-nitrophenyl) hydrogen phosphate (C7H7NO6P) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester group. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Methyl (4-nitrophenyl) hydrogen phosphate 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.
