Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 215.99 g/mol gives 2,4-Difluoro-5-isopropoxyphenylboronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,4-Difluoro-5-isopropoxyphenylboronic acid (CAS 2096333-88-7) is a high-purity analytical reference standard with the molecular formula C9H11BF2O3 and a molecular weight of 215.99 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2,4-Difluoro-5-isopropoxyphenylboronic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 215.99 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.
