Chemical Structure
Description
The occurrence of 1,5-Naphthyridine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Naphthyridine hydrochloride (CAS 698999-42-7) is a high-purity analytical reference standard with the molecular formula C8H6N2HCl and a molecular weight of 166.61 g/mol.
Based on its molecular formula C8H6N2HCl, 1,5-Naphthyridine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 166.61 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.
