5-[4-(trifluoromethyl)phenyl]thiophene-2-carbaldehyde CAS 343604-31-9

Description

The occurrence of 5-[4-(trifluoromethyl)phenyl]thiophene-2-carbaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-[4-(trifluoromethyl)phenyl]thiophene-2-carbaldehyde (CAS 343604-31-9) is a high-purity analytical reference standard with the molecular formula C12H7F3OS and a molecular weight of 256.24 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 5-[4-(trifluoromethyl)phenyl]thiophene-2-carbaldehyde is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 256.24 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).

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.
