Chemical Structure

4-(Difluoromethyl)-3-iodo-5-nitropicolinic acid CAS 1807142-55-7 chemical structure

Description

4-(Difluoromethyl)-3-iodo-5-nitropicolinic acid (CAS 1807142-55-7) is a high-purity analytical reference standard with the molecular formula C7H3F2IN2O4 and a molecular weight of 344.01 g/mol.

4-(Difluoromethyl)-3-iodo-5-nitropicolinic acid (C7H3F2IN2O4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.

CATO manufactures 4-(Difluoromethyl)-3-iodo-5-nitropicolinic acid 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.
