Chemical Structure
Description
[MetO18]-Teriparatide (CAS CATO-C4X-21857), molecular formula C182H293N55O52S2 and molecular weight 4147.74 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, [MetO18]-Teriparatide is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 4147.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 [MetO18]-Teriparatide 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.
