4-Chloro-6-iodopicolinaldehyde (CAS 1289060-75-8) is a high-purity analytical reference standard with the molecular formula C6H3ClINO and a molecular weight of 267.45 g/mol.
4-Chloro-6-iodopicolinaldehyde (C6H3ClINO) contains an amide group, a hydroxyl group, an ether linkage, chlorine/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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 4-Chloro-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.
