Description
CATO manufactures 2-Bromo-3-methylisonicotinaldehyde 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.
2-Bromo-3-methylisonicotinaldehyde (CAS 1227575-75-8) is a high-purity analytical reference standard with the molecular formula C7H6BrNO and a molecular weight of 200.03 g/mol.
2-Bromo-3-methylisonicotinaldehyde (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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
