Chemical Structure
Description
(4-((4h-1,2,4-Triazol-4-yl)carbamoyl)phenyl)boronic acid hydrochloride (CAS 850568-29-5) is a high-purity analytical reference standard with the molecular formula C9H9BN4O3HCl and a molecular weight of 268.46 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (4-((4h-1,2,4-Triazol-4-yl)carbamoyl)phenyl)boronic acid hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
