Chemical Structure

1,2-Diphenylpent-4-yn-1-one CAS 38940-37-3 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 1,2-Diphenylpent-4-yn-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1,2-Diphenylpent-4-yn-1-one (CAS 38940-37-3) is a high-purity analytical reference standard with the molecular formula C17H14O and a molecular weight of 234.29 g/mol.

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

As a certified reference material (CRM), 1,2-Diphenylpent-4-yn-1-one 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.
