Chemical Structure
Description
5-Bromo-4,4-dimethyl-1,2,3,4-tetrahydroisoquinoline hydrochloride (CAS 1203683-41-3) is a high-purity analytical reference standard with the molecular formula C11H14BrNHCl and a molecular weight of 276.60 g/mol.
Structurally, 5-Bromo-4,4-dimethyl-1,2,3,4-tetrahydroisoquinoline hydrochloride (C11H14BrNHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 276.60 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 5-Bromo-4,4-dimethyl-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.
