4-Cyanophenylacetylene 4-ethynyl-benzonitrile 4-Ethynylbenzonitrile 3032-92-6 CAS 3032-92-6

Description

As a certified reference material (CRM), 4-Cyanophenylacetylene 4-ethynyl-benzonitrile 4-Ethynylbenzonitrile 3032-92-6 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.

4-Cyanophenylacetylene 4-ethynyl-benzonitrile 4-Ethynylbenzonitrile 3032-92-6 (CAS 3032-92-6), molecular formula C9H11N and molecular weight 133.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Cyanophenylacetylene 4-ethynyl-benzonitrile 4-Ethynylbenzonitrile 3032-92-6 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.19 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).

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.
