Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3,5-Diiodo-Tyr2,Arg8)-Vasopressin (CAS 63441-67-8), molecular formula C46H63I2N15O12S2 and molecular weight 1336.00 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, iodine substitution, (3,5-Diiodo-Tyr2,Arg8)-Vasopressin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1336.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
