(3-Aminopyridin-4-yl)boronic acid CAS 2096337-23-2 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.

(3-Aminopyridin-4-yl)boronic acid (CAS 2096337-23-2) is a high-purity analytical reference standard with the molecular formula C5H7BN2O2 and a molecular weight of 137.93 g/mol.

Structurally, (3-Aminopyridin-4-yl)boronic acid (C5H7BN2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 137.93 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.
