Chemical Structure

2-Methoxy-5-(trifluoromethyl)isonicotinaldehyde CAS 1211531-20-2 chemical structure

Description

2-Methoxy-5-(trifluoromethyl)isonicotinaldehyde (CAS 1211531-20-2) is a high-purity analytical reference standard with the molecular formula C8H6F3NO2 and a molecular weight of 205.13 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Methoxy-5-(trifluoromethyl)isonicotinaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 205.13 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).

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.
