Chemical Structure

Sodium pyroantimonate CAS 12507-68-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 500.27 g/mol gives Sodium pyroantimonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Sodium pyroantimonate (CAS 12507-68-5) is a high-purity analytical reference standard with the molecular formula NaO7Sb3 and a molecular weight of 500.27 g/mol.

Owing to an inorganic composition, Sodium pyroantimonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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 Sodium pyroantimonate 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.
