Methacryloxydiphenylantimony CAS 5613-66-1 chemical structure

Description

As a certified reference material (CRM), Methacryloxydiphenylantimony 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.

CATO supplies Methacryloxydiphenylantimony (CAS 5613-66-1), a certified reference material (molecular formula C16H15O2Sb, MW 361.05 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H15O2Sb, Methacryloxydiphenylantimony contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
