Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 497.48 g/mol gives Phenolphthalein monophosphate (dicyclohexylammonium) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Phenolphthalein monophosphate (dicyclohexylammonium) (CAS 14815-59-9), a certified reference material (molecular formula C20H15O7PC6H13N, MW 497.48 g/mol) for analytical method development and quality control.
Phenolphthalein monophosphate (dicyclohexylammonium) (C20H15O7PC6H13N) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. 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), Phenolphthalein monophosphate (dicyclohexylammonium) 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.
