Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1468.52 g/mol gives Hirudin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Hirudin (CAS 113274-56-9), molecular formula C66H93N13O25 and molecular weight 1468.52 g/mol, is a CATO reference standard with documented purity and traceability.
Hirudin (C66H93N13O25) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 Hirudin 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.
