Chemical Structure
Description
The occurrence of 3-Chloro-7-iodoisoquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-7-iodoisoquinoline (CAS 1841079-91-1), molecular formula C9H5ClIN and molecular weight 289.50 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H5ClIN, 3-Chloro-7-iodoisoquinoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Chloro-7-iodoisoquinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
