Chemical Structure
Description
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.
2-Methylimidazo[1,2-a]pyridin-5-amine hydrochloride (CAS 3931-67-7), molecular formula C8H9N3HCl and molecular weight 183.64 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methylimidazo[1,2-a]pyridin-5-amine hydrochloride (C8H9N3HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
