Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

CATO supplies O7TSZ97GEP 7789-77-7 Calcium monohydrogen phosphate dihydrate Calcium phosphate, dibasic, dihydrate Dicalcium phosphate dihydrate Phosphoric acid, calcium salt (1:1), dihydrate Calcium phosphate dihydrate, dibasic [USP:JAN] Calcium-hydrogenphosphat-2-wasser Aksepillen Eunova UNII-O7TSZ97GEP Calcium phosphate dihydrate, dibasic Calstar D.C.P. (CAS 7789-77-7), a certified reference material (molecular formula HO4PCaH2O, MW 154.07 g/mol) for analytical method development and quality control.

The molecular framework of O7TSZ97GEP 7789-77-7 Calcium monohydrogen phosphate dihydrate Calcium phosphate, dibasic, dihydrate Dicalcium phosphate dihydrate Phosphoric acid, calcium salt (1:1), dihydrate Calcium phosphate dihydrate, dibasic [USP:JAN] Calcium-hydrogenphosphat-2-wasser Aksepillen Eunova UNII-O7TSZ97GEP Calcium phosphate dihydrate, dibasic Calstar D.C.P. (HO4PCaH2O) is characterized by a phosphate ester group. 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.

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.
