Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Ethylpyridine-3-boronic Acid Pinacol Ester.
2-Ethylpyridine-3-boronic Acid Pinacol Ester (CAS 1494670-02-8) is a high-purity analytical reference standard with the molecular formula C13H20BNO2 and a molecular weight of 233.11 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Ethylpyridine-3-boronic Acid Pinacol Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.11 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.
