Chemical Structure
Description
CATO supplies Methyl (4-nitrophenyl) hexylphosphonate (CAS 259827-72-0), a certified reference material (molecular formula C13H20NO5P, MW 301.28 g/mol) for analytical method development and quality control.
Methyl (4-nitrophenyl) hexylphosphonate (C13H20NO5P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Methyl (4-nitrophenyl) hexylphosphonate 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.
