Chemical Structure
Description
The occurrence of Clonidine-d4 Hydrochloride is closely related to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Clonidine-d4 Hydrochloride (CAS 67151-02-4) is a high-purity analytical reference standard with the molecular formula C9H5D4Cl2N3HCl and a molecular weight of 270.57 g/mol.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, Clonidine-d4 Hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 270.57 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.
