Chemical Structure
Description
Structurally, (Deamino-Cys1,Lys8)-Oxytocin trifluoroacetate salt (C43H66N12O12S2C2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 1121.22 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).
(Deamino-Cys1,Lys8)-Oxytocin trifluoroacetate salt (CAS 25529-45-7) is a high-purity analytical reference standard with the molecular formula C43H66N12O12S2C2HF3O2 and a molecular weight of 1121.22 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
