Chemical Structure
Description
The occurrence of Cecropin B (free acid) trifluoroacetate salt is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Cecropin B (free acid) trifluoroacetate salt (CAS 203265-23-0), molecular formula C176H302N52O41SC2HF3O2 and molecular weight 3948.76 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Cecropin B (free acid) trifluoroacetate salt (C176H302N52O41SC2HF3O2) 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 52.0, corresponding to approximately 52 ring(s) or double-bond equivalent(s). With a molecular weight of 3948.76 g/mol, it falls into the high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
