Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methoxypyridine-2,3-diamine Dihydrochloride.
6-Methoxypyridine-2,3-diamine Dihydrochloride (CAS 94166-62-8), molecular formula C6H9N3OHCl and molecular weight 175.62 g/mol, is a CATO reference standard with documented purity and traceability.
6-Methoxypyridine-2,3-diamine Dihydrochloride (C6H9N3OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
