A,A-Diphenyl-benzeneacetaldehyde CAS 42365-04-8 chemical structure

Description

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

A,A-Diphenyl-benzeneacetaldehyde (CAS 42365-04-8) is a high-purity analytical reference standard with the molecular formula C20H16O and a molecular weight of 272.34 g/mol.

A,A-Diphenyl-benzeneacetaldehyde (C20H16O) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), A,A-Diphenyl-benzeneacetaldehyde 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.
