Chemical Structure
Description
The occurrence of 1,4-Dithia-7-azaspiro[4.4]nonane, HCl is closely related to sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,4-Dithia-7-azaspiro[4.4]nonane, HCl (CAS 958451-81-5) is a high-purity analytical reference standard with the molecular formula C6H11NS2HCl and a molecular weight of 197.74 g/mol.
1,4-Dithia-7-azaspiro[4.4]nonane, HCl (C6H11NS2HCl) contains sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
