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 3',6'-Dichloro-4,5,6,7-tetrafluoro-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one.
CATO supplies 3',6'-Dichloro-4,5,6,7-tetrafluoro-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one (CAS 1044164-77-3), a certified reference material (molecular formula C20H6Cl2F4O3, MW 441.16 g/mol) for analytical method development and quality control.
3',6'-Dichloro-4,5,6,7-tetrafluoro-3H-spiro[isobenzofuran-1,9'-xanthen]-3-one (C20H6Cl2F4O3) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
CATO manufactures 3',6'-Dichloro-4,5,6,7-tetrafluoro-3H-spiro[isobenzofuran-1,9'-xanthen]-3-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.
