Chemical Structure
Description
The occurrence of Cyproheptadine Hydrochloride Sesquihydrate is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Cyproheptadine Hydrochloride Sesquihydrate (CAS 41354-29-4), molecular formula C21H21NHClH2O and molecular weight 341.88 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H21NHClH2O, Cyproheptadine Hydrochloride Sesquihydrate contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 341.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
