Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 193.63 g/mol gives 1-Chloro-6-methoxyisoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Chloro-6-methoxyisoquinoline (CAS 132997-77-4), molecular formula C10H8ClNO and molecular weight 193.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-Chloro-6-methoxyisoquinoline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 1-Chloro-6-methoxyisoquinoline 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.
