Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
FITC-εAhx-Gly-Arg-Gly-Asp-Ser-Pro-OH trifluoroacetate salt (CAS 2022956-44-9) is a high-purity analytical reference standard with the molecular formula C49H59N11O16SC2HF3O2 and a molecular weight of 1204.15 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, FITC-εAhx-Gly-Arg-Gly-Asp-Ser-Pro-OH trifluoroacetate salt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1204.15 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.
