CATO manufactures Angiotensin II 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.
Angiotensin II (CAS 4474-91-3(Free Base)), molecular formula C50H71N13O12C2H4O2 and molecular weight 1106.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Angiotensin II is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1106.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
