Chemical Structure
Description
N-Methyl-1-(1-methyl-1,2,3,4-tetrahydro-6-quinolinyl)methanamine oxalate (CAS 1260789-19-2), molecular formula C12H18N2C2H2O4 and molecular weight 280.32 g/mol, is a CATO reference standard with documented purity and traceability.
N-Methyl-1-(1-methyl-1,2,3,4-tetrahydro-6-quinolinyl)methanamine oxalate (C12H18N2C2H2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
