Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 400.55 g/mol gives Ophiobolin A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ophiobolin A (CAS 4611-05-6) is a high-purity analytical reference standard with the molecular formula C25H36O4 and a molecular weight of 400.55 g/mol.
Ophiobolin A (C25H36O4) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 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 Ophiobolin A 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.
