Description
As a certified reference material (CRM), Methyl 5-amino-4,6-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.
Methyl 5-amino-4,6-dichloropicolinate (CAS 1805930-73-7) is a high-purity analytical reference standard with the molecular formula C7H6Cl2N2O2 and a molecular weight of 221.04 g/mol.
Methyl 5-amino-4,6-dichloropicolinate (C7H6Cl2N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
