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.
5-(1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-7-yl)pentanoic acid (CAS 1268335-65-4) is a high-purity analytical reference standard with the molecular formula C12H15BO4 and a molecular weight of 234.06 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 5-(1-Hydroxy-1,3-dihydrobenzo[c][1,2]oxaborol-7-yl)pentanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.06 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.
