Chemical Structure
Description
5-Bromo-6-methylpyridine-2-carboxaldehyde (CAS 137778-18-8), molecular formula C7H6BrNO and molecular weight 200.03 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-6-methylpyridine-2-carboxaldehyde (C7H6BrNO) 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.
CATO manufactures 5-Bromo-6-methylpyridine-2-carboxaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
