Chemical Structure

(Ethynyloxy)benzene CAS 4279-76-9 chemical structure

Description

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.

(Ethynyloxy)benzene (CAS 4279-76-9), molecular formula C8H6O and molecular weight 118.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Ethynyloxy)benzene (C8H6O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

CATO manufactures (Ethynyloxy)benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
