Chemical Structure

Biphenyl CAS 92-52-4 chemical structure

Description

The occurrence of Biphenyl is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Biphenyl (CAS 92-52-4), a certified reference material (molecular formula C12H10, MW 154.21 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H10, Biphenyl contains an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 154.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Biphenyl 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.
