Chemical Structure
Description
The occurrence of (4-(4-(Tert-butoxycarbonyl)piperazine-1-carbonyl)-3-chlorophenyl)boronic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-(4-(Tert-butoxycarbonyl)piperazine-1-carbonyl)-3-chlorophenyl)boronic acid (CAS 1704097-56-2), molecular formula C16H22BClN2O5 and molecular weight 368.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (4-(4-(Tert-butoxycarbonyl)piperazine-1-carbonyl)-3-chlorophenyl)boronic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 368.62 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.
