4-Methyl-2,3,4,5,6,7-hexahydro-1H-pyrido[3,2,1-ij]quinolin-4-ium hydroxide CAS 865276-12-6

Description

Compared with other compounds in its class, the molecular weight of 205.30 g/mol gives 4-Methyl-2,3,4,5,6,7-hexahydro-1H-pyrido[3,2,1-ij]quinolin-4-ium hydroxide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Methyl-2,3,4,5,6,7-hexahydro-1H-pyrido[3,2,1-ij]quinolin-4-ium hydroxide (CAS 865276-12-6) is a high-purity analytical reference standard with the molecular formula C13H18NHO and a molecular weight of 205.30 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Methyl-2,3,4,5,6,7-hexahydro-1H-pyrido[3,2,1-ij]quinolin-4-ium hydroxide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 205.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
