Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-({3-methyl-[1,2,4]triazolo[4,3-a]pyrazin-8-yl}oxy)pyridine-3-carboxylic acid dihydrochloride.
5-({3-methyl-[1,2,4]triazolo[4,3-a]pyrazin-8-yl}oxy)pyridine-3-carboxylic acid dihydrochloride (CAS 1421604-98-9) is a high-purity analytical reference standard with the molecular formula C12H9N5O3HCl and a molecular weight of 307.69 g/mol.
5-({3-methyl-[1,2,4]triazolo[4,3-a]pyrazin-8-yl}oxy)pyridine-3-carboxylic acid dihydrochloride (C12H9N5O3HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
