Chemical Structure

Violanthrone 79 CAS 85652-50-2 chemical structure

Description

As a certified reference material (CRM), Violanthrone 79 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 Violanthrone 79 (CAS 85652-50-2), a certified reference material (molecular formula C50H48O4, MW 712.91 g/mol) for analytical method development and quality control.

Violanthrone 79 (C50H48O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
