Chemical Structure
Description
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.
[D-Cys6]-Carbetocin TFA (CAS CATO-C4X-191127) is a high-purity analytical reference standard with the molecular formula C45H69N11O12SC2HF3O2 and a molecular weight of 1102.19 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, [D-Cys6]-Carbetocin TFA is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1102.19 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
