Chemical Structure
Description
The occurrence of 6,8-Dichloro-1,2,3,4-tetrahydroisoquinoline Hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6,8-Dichloro-1,2,3,4-tetrahydroisoquinoline Hydrochloride (CAS 73075-50-0) is a high-purity analytical reference standard with the molecular formula C9H9Cl2NHCl and a molecular weight of 238.54 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 6,8-Dichloro-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 238.54 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6,8-Dichloro-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.
