Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Chloro-3-(4-ethylpiperazine-1-carbonyl)phenyl)boronic acid.
CATO supplies (4-Chloro-3-(4-ethylpiperazine-1-carbonyl)phenyl)boronic acid (CAS 1704074-11-2), a certified reference material (molecular formula C13H18BClN2O3, MW 296.56 g/mol) for analytical method development and quality control.
Structurally, (4-Chloro-3-(4-ethylpiperazine-1-carbonyl)phenyl)boronic acid (C13H18BClN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 296.56 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.
As a certified reference material (CRM), (4-Chloro-3-(4-ethylpiperazine-1-carbonyl)phenyl)boronic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
