2-Ethynyl-2'-methoxy-1,1'-biphenyl CAS 445262-74-8

Description

Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2-Ethynyl-2'-methoxy-1,1'-biphenyl is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

2-Ethynyl-2'-methoxy-1,1'-biphenyl (CAS 445262-74-8), molecular formula C15H12O and molecular weight 208.26 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
