Calcium;1-naphthyl hydrogen phosphate CAS 57775-19-6

Description

The occurrence of Calcium;1-naphthyl hydrogen phosphate is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Calcium;1-naphthyl hydrogen phosphate (CAS 57775-19-6), molecular formula C10H8O4PCaH2O and molecular weight 281.24 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Calcium;1-naphthyl hydrogen phosphate (C10H8O4PCaH2O) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
