Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 340.28 g/mol gives Sofosbuvir Impurity 98 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sofosbuvir Impurity 98 (CAS 111955-47-6), a certified reference material (molecular formula C18H12O7, MW 340.28 g/mol) for analytical method development and quality control.
Sofosbuvir Impurity 98 (C18H12O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Sofosbuvir Impurity 98 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.
