Chemical Structure
Description
The molecular framework of Methyl 3-bromo-4-oxopiperidine-1-carboxylate (C7H10BrNO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Methyl 3-bromo-4-oxopiperidine-1-carboxylate (CAS 1891261-14-5) is a high-purity analytical reference standard with the molecular formula C7H10BrNO3 and a molecular weight of 236.06 g/mol.
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), Methyl 3-bromo-4-oxopiperidine-1-carboxylate 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.
