Chemical Structure
Description
The occurrence of Triammonium phosphate trihydrate is closely related to a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Triammonium phosphate trihydrate (CAS 25447-33-0), a certified reference material (molecular formula H3O4PH2OH3N, MW 133.04 g/mol) for analytical method development and quality control.
Based on its molecular formula H3O4PH2OH3N, Triammonium phosphate trihydrate contains a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 133.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Triammonium phosphate trihydrate 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.
