N'-[(1E)-{4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene]pyridine-4-carbohydrazide CAS 339018-45-0 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 N'-[(1E)-{4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene]pyridine-4-carbohydrazide.

N'-[(1E)-{4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene]pyridine-4-carbohydrazide (CAS 339018-45-0) is a high-purity analytical reference standard with the molecular formula C18H15ClN4O3S and a molecular weight of 402.85 g/mol.

N'-[(1E)-{4-[(2-chloro-1,3-thiazol-5-yl)methoxy]-3-methoxyphenyl}methylidene]pyridine-4-carbohydrazide (C18H15ClN4O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
