Description
As a certified reference material (CRM), Ledipasvir Impurity-3 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Ledipasvir Impurity-3 (CAS 1256388-50-7), molecular formula C29H29BrF2N4O3 and molecular weight 599.47 g/mol, is a CATO reference standard with documented purity and traceability.
Ledipasvir Impurity-3 (C29H29BrF2N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
