1-(4-Chloro-5-(naphthalen-2-yl)thiophen-2-yl)ethan-1-one CAS 1309597-90-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 286.78 g/mol gives 1-(4-Chloro-5-(naphthalen-2-yl)thiophen-2-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(4-Chloro-5-(naphthalen-2-yl)thiophen-2-yl)ethan-1-one (CAS 1309597-90-7) is a high-purity analytical reference standard with the molecular formula C16H11ClOS and a molecular weight of 286.78 g/mol.

1-(4-Chloro-5-(naphthalen-2-yl)thiophen-2-yl)ethan-1-one (C16H11ClOS) contains sulfur-containing functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 1-(4-Chloro-5-(naphthalen-2-yl)thiophen-2-yl)ethan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
