2-Fluoro-5-(5-formylthiophen-3-yl)benzoic acid CAS 1261909-30-1

Description

The occurrence of 2-Fluoro-5-(5-formylthiophen-3-yl)benzoic acid is closely related to a sulfone group, a carboxylic acid group, 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.

2-Fluoro-5-(5-formylthiophen-3-yl)benzoic acid (CAS 1261909-30-1) is a high-purity analytical reference standard with the molecular formula C12H7FO3S and a molecular weight of 250.25 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-Fluoro-5-(5-formylthiophen-3-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.25 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
