Chemical Structure

Isoxazol-3-yl dihydrogen phosphate CAS 36190-19-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 165.04 g/mol gives Isoxazol-3-yl dihydrogen phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Isoxazol-3-yl dihydrogen phosphate (CAS 36190-19-9), a certified reference material (molecular formula C3H4NO5P, MW 165.04 g/mol) for analytical method development and quality control.

The molecular framework of Isoxazol-3-yl dihydrogen phosphate (C3H4NO5P) is characterized by an amide group, a phosphate ester group, a carboxylic acid group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Isoxazol-3-yl dihydrogen 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.
