Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-3-iodobenzaldehyde (CAS 1261449-85-7) is a high-purity analytical reference standard with the molecular formula C7H4ClIO and a molecular weight of 266.46 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system, 2-Chloro-3-iodobenzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 2-Chloro-3-iodobenzaldehyde 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.
