Chemical Structure
Description
The molecular framework of 4-Bromo-3-formyl-2-(N-piperidinyl)pyridine (C11H13BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
4-Bromo-3-formyl-2-(N-piperidinyl)pyridine (CAS 1092352-43-6) is a high-purity analytical reference standard with the molecular formula C11H13BrN2O and a molecular weight of 269.14 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), 4-Bromo-3-formyl-2-(N-piperidinyl)pyridine 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.
