Chemical Structure

1,2-Diphenylethyleneoxide CAS 17619-97-5 chemical structure

Description

As a certified reference material (CRM), 1,2-Diphenylethyleneoxide 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.

1,2-Diphenylethyleneoxide (CAS 17619-97-5), molecular formula C14H12O and molecular weight 196.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,2-Diphenylethyleneoxide is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
