Description
CATO supplies Methyl 5-bromo-3,6-dichloropicolinate (CAS 1820664-86-5), a certified reference material (molecular formula C7H4BrCl2NO2, MW 284.92 g/mol) for analytical method development and quality control.
Methyl 5-bromo-3,6-dichloropicolinate (C7H4BrCl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. 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.
As a certified reference material (CRM), Methyl 5-bromo-3,6-dichloropicolinate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
