Chemical Structure

Phosphoric acid, lanthanum(3+) salt CAS 13778-59-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phosphoric acid, lanthanum(3+) salt.

Phosphoric acid, lanthanum(3+) salt (CAS 13778-59-1), molecular formula LaO4P and molecular weight 233.88 g/mol, is a CATO reference standard with documented purity and traceability.

Phosphoric acid, lanthanum(3+) salt (LaO4P) contains a phosphate ester group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

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.
