Chemical Structure

Phenyl-d5-acetylene CAS 25837-46-1 chemical structure

Description

The molecular framework of Phenyl-d5-acetylene (C8HD5) is characterized by deuterium isotope labeling, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, 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).

Phenyl-d5-acetylene (CAS 25837-46-1) is a high-purity analytical reference standard with the molecular formula C8HD5 and a molecular weight of 107.16 g/mol.

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.

CATO manufactures Phenyl-d5-acetylene 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.
