Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Calcitonin (9-32) (free acid) (human) (CAS 762263-16-1) is a high-purity analytical reference standard with the molecular formula C121H176N30O35 and a molecular weight of 2610.91 g/mol.
Structurally, Calcitonin (9-32) (free acid) (human) (C121H176N30O35) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 49.0, corresponding to approximately 49 ring(s) or double-bond equivalent(s). With a molecular weight of 2610.91 g/mol, it falls into the high-molecular-weight range. 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).
CATO manufactures Calcitonin (9-32) (free acid) (human) 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.
