Chemical Structure
Description
(2-(Sec-butyl)-5-fluoropyridin-4-yl)boronic acid (CAS 2225153-49-9) is a high-purity analytical reference standard with the molecular formula C9H13BFNO2 and a molecular weight of 197.01 g/mol.
Structurally, (2-(Sec-butyl)-5-fluoropyridin-4-yl)boronic acid (C9H13BFNO2) 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 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 197.01 g/mol, it falls into the medium-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).
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.
