Chemical Structure
Description
anthracene-9-carbonyl chloride (CAS 16331-52-5) is a high-purity analytical reference standard with the molecular formula C15H9ClO and a molecular weight of 240.68 g/mol.
Based on its molecular formula C15H9ClO, anthracene-9-carbonyl chloride contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 240.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures anthracene-9-carbonyl chloride 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.
