Chemical Structure

Lead phosphite-dibasic CAS 1344-40-7 chemical structure

Description

As a certified reference material (CRM), Lead phosphite-dibasic meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Lead phosphite-dibasic (CAS 1344-40-7) is a high-purity analytical reference standard with the molecular formula PbHO3P and a molecular weight of 287.18 g/mol.

Based on its molecular formula PbHO3P, Lead phosphite-dibasic contains a phosphonate group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 287.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
