Chemical Structure

1-(1,5-Dimethyl-1H-pyrrol-2-yl)-2,2,2-trifluoroethanone CAS 74889-29-5 chemical structure

Description

The occurrence of 1-(1,5-Dimethyl-1H-pyrrol-2-yl)-2,2,2-trifluoroethanone is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(1,5-Dimethyl-1H-pyrrol-2-yl)-2,2,2-trifluoroethanone (CAS 74889-29-5), molecular formula C8H8F3NO and molecular weight 191.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 1-(1,5-Dimethyl-1H-pyrrol-2-yl)-2,2,2-trifluoroethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 191.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
