5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1h-pyrrolo[2,3-b]pyridine-3-carbonitrile (CAS 1620575-06-5), molecular formula C14H16BN3O2 and molecular weight 269.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1h-pyrrolo[2,3-b]pyridine-3-carbonitrile (C14H16BN3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 269.11 g/mol, it falls into the medium-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).
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.
