Chemical Structure
Description
The occurrence of 6-Chloro-5-fluoro-1,2,3,4-tetrahydroisoquinoline hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Chloro-5-fluoro-1,2,3,4-tetrahydroisoquinoline hydrochloride (CAS 1956334-35-2), molecular formula C9H9ClFNHCl and molecular weight 222.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 6-Chloro-5-fluoro-1,2,3,4-tetrahydroisoquinoline hydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.08 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.
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 6-Chloro-5-fluoro-1,2,3,4-tetrahydroisoquinoline hydrochloride 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.
