Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 5-Chloro-2-hydrazineyl-4-tosylthiazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.79 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.
