Chemical Structure

2-(p-Tolyl)-3-(trifluoromethyl)benzofuran CAS 821769-95-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(p-Tolyl)-3-(trifluoromethyl)benzofuran.

2-(p-Tolyl)-3-(trifluoromethyl)benzofuran (CAS 821769-95-3) is a high-purity analytical reference standard with the molecular formula C16H11F3O and a molecular weight of 276.25 g/mol.

Structurally, 2-(p-Tolyl)-3-(trifluoromethyl)benzofuran (C16H11F3O) contains a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 276.25 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
