2,4-Dimethylquinoline CAS 1198-37-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 157.21 g/mol gives 2,4-Dimethylquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,4-Dimethylquinoline (CAS 1198-37-4), molecular formula C11H11N and molecular weight 157.21 g/mol, is a CATO reference standard with documented purity and traceability.

2,4-Dimethylquinoline (C11H11N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
