Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-(Difluoromethyl)isoxazole-5-carbaldehyde (CAS 2344685-03-4), a certified reference material (molecular formula C5H3F2NO2, MW 147.08 g/mol) for analytical method development and quality control.
Structurally, 3-(Difluoromethyl)isoxazole-5-carbaldehyde (C5H3F2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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 147.08 g/mol, it falls into the low-molecular-weight range. 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).
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.
