Chemical Structure
Description
6-Chloro-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (C14H19Cl) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
6-Chloro-1,1,4,4-tetramethyl-1,2,3,4-tetrahydronaphthalene (CAS 27452-14-8) is a high-purity analytical reference standard with the molecular formula C14H19Cl and a molecular weight of 222.75 g/mol.
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.
