Chemical Structure

3-(Trifluoromethyl)pyridine CAS 3796-23-4 chemical structure

Description

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.

3-(Trifluoromethyl)pyridine (CAS 3796-23-4) is a high-purity analytical reference standard with the molecular formula C6H4F3N and a molecular weight of 147.10 g/mol.

Structurally, 3-(Trifluoromethyl)pyridine (C6H4F3N) contains a nitrile group, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 147.10 g/mol, it falls into the low-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.
