Chemical Structure

Lead stearate (dibasic) CAS 56189-09-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 490.68 g/mol gives Lead stearate (dibasic) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Lead stearate (dibasic) (CAS 56189-09-4), molecular formula C18H35O2Pb and molecular weight 490.68 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Lead stearate (dibasic) (C18H35O2Pb) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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

CATO manufactures Lead stearate (dibasic) 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.
