Chemical Structure
Description
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.
CATO supplies acetic-phosphoricanhydride (CAS 590-54-5), a certified reference material (molecular formula C2H5O5P, MW 140.03 g/mol) for analytical method development and quality control.
The molecular framework of acetic-phosphoricanhydride (C2H5O5P) is characterized by a phosphate ester group, a carboxylic acid group, an ether linkage. 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.
As a certified reference material (CRM), acetic-phosphoricanhydride 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.
