Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 246.53 g/mol gives 7-Bromo-3,4-dihydroisoquinoline hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Bromo-3,4-dihydroisoquinoline hydrochloride (CAS 16516-67-9) is a high-purity analytical reference standard with the molecular formula C9H8BrNHCl and a molecular weight of 246.53 g/mol.
7-Bromo-3,4-dihydroisoquinoline hydrochloride (C9H8BrNHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 7-Bromo-3,4-dihydroisoquinoline 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.
