Chemical Structure
Description
1-Methyl-9H-pyrido[3,4-b]indole hydrochloride (CAS 21655-84-5), molecular formula C12H10N2HCl and molecular weight 218.68 g/mol, is a CATO reference standard with documented purity and traceability.
1-Methyl-9H-pyrido[3,4-b]indole hydrochloride (C12H10N2HCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
