Chemical Structure

4′-(Phenylethynyl)acetophenone CAS 1942-31-0 chemical structure

Description

CATO supplies 4′-(Phenylethynyl)acetophenone (CAS 1942-31-0), a certified reference material (molecular formula C16H24O, MW 232.36 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 4′-(Phenylethynyl)acetophenone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 232.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 4′-(Phenylethynyl)acetophenone 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.
