Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S-cis)-4-(3,4-Dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenol.
(1S-cis)-4-(3,4-Dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenol (CAS 167026-37-1) is a high-purity analytical reference standard with the molecular formula C16H14Cl2O and a molecular weight of 293.19 g/mol.
(1S-cis)-4-(3,4-Dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthalenol (C16H14Cl2O) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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. 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.
