Chemical Structure
Description
6-methyl-5,6,7,8-tetrahydro-1,6-naphthyridine (CAS 14903-73-2), molecular formula C9H12N2 and molecular weight 148.20 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H12N2, 6-methyl-5,6,7,8-tetrahydro-1,6-naphthyridine contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 148.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
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.
