Chemical Structure
Description
The occurrence of 4-Chloro-5-iodopyrimidine hydrochloride is closely related to a nitrile group, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-5-iodopyrimidine hydrochloride (CAS 1328624-24-3), molecular formula C4H2ClIN2HCl and molecular weight 276.88 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Chloro-5-iodopyrimidine hydrochloride (C4H2ClIN2HCl) contains a nitrile group, chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 276.88 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
