Chemical Structure

di-tert-butyl (4-(hydroxymethyl)phenyl) phosphate CAS 857896-79-8 chemical structure

Description

The occurrence of di-tert-butyl (4-(hydroxymethyl)phenyl) phosphate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies di-tert-butyl (4-(hydroxymethyl)phenyl) phosphate (CAS 857896-79-8), a certified reference material (molecular formula C15H25O5P, MW 316.33 g/mol) for analytical method development and quality control.

The molecular framework of di-tert-butyl (4-(hydroxymethyl)phenyl) phosphate (C15H25O5P) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), di-tert-butyl (4-(hydroxymethyl)phenyl) 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.
