Chemical Structure

(5-Cyano-2-methoxypyridin-3-yl)boronic acid CAS 1231231-15-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 177.95 g/mol gives (5-Cyano-2-methoxypyridin-3-yl)boronic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(5-Cyano-2-methoxypyridin-3-yl)boronic acid (CAS 1231231-15-4), molecular formula C7H7BN2O3 and molecular weight 177.95 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (5-Cyano-2-methoxypyridin-3-yl)boronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.95 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
