Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N4-[4-phenyl-5-(trifluoromethyl)-3-thienyl]-2,6-dichloroisonicotinamide.
N4-[4-phenyl-5-(trifluoromethyl)-3-thienyl]-2,6-dichloroisonicotinamide (CAS 256488-39-8) is a high-purity analytical reference standard with the molecular formula C17H9Cl2F3N2OS and a molecular weight of 417.23 g/mol.
Structurally, N4-[4-phenyl-5-(trifluoromethyl)-3-thienyl]-2,6-dichloroisonicotinamide (C17H9Cl2F3N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 417.23 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
