Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 312.23 g/mol gives Tetrakis(hydroxymethyl)phosphonium sulfate urea distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Tetrakis(hydroxymethyl)phosphonium sulfate urea (CAS 63502-25-0), a certified reference material (molecular formula C4H12O4PHO4SCH4N2O, MW 312.23 g/mol) for analytical method development and quality control.
The molecular framework of Tetrakis(hydroxymethyl)phosphonium sulfate urea (C4H12O4PHO4SCH4N2O) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, a phosphate ester group. 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.
CATO manufactures Tetrakis(hydroxymethyl)phosphonium sulfate urea under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
