Chemical Structure
Description
3-Methyl-5,6,7,8-tetrahydro-1,6-naphthyridine (CAS 83100-02-1), molecular formula C9H12N2 and molecular weight 148.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-Methyl-5,6,7,8-tetrahydro-1,6-naphthyridine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 148.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
