3,5-Dimethyl-[1,1'-biphenyl]-2-ol CAS 21389-90-2

Description

3,5-Dimethyl-[1,1'-biphenyl]-2-ol (CAS 21389-90-2), molecular formula C14H14O and molecular weight 198.26 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,5-Dimethyl-[1,1'-biphenyl]-2-ol (C14H14O) contains a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 198.26 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures 3,5-Dimethyl-[1,1'-biphenyl]-2-ol 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.
