Chemical Structure
Description
As a certified reference material (CRM), 4-Bromopicolinaldehyde 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.
4-Bromopicolinaldehyde (CAS 131747-63-2), molecular formula C6H4BrNO and molecular weight 186.01 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromopicolinaldehyde (C6H4BrNO) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
