Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-6-iodopicolinaldehyde.
4-Bromo-6-iodopicolinaldehyde (CAS 1289136-29-3), molecular formula C6H3BrINO and molecular weight 311.90 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-6-iodopicolinaldehyde (C6H3BrINO) contains an amide group, a hydroxyl group, an ether linkage, bromine/iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-Bromo-6-iodopicolinaldehyde 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.
