Chemical Structure

7-Hydroxy-1,2,3,4-tetrahydroisoquinoline Hydrobromide CAS 110192-19-3 chemical structure

Description

The occurrence of 7-Hydroxy-1,2,3,4-tetrahydroisoquinoline Hydrobromide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

7-Hydroxy-1,2,3,4-tetrahydroisoquinoline Hydrobromide (CAS 110192-19-3), molecular formula C9H11NOHBr and molecular weight 230.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Hydroxy-1,2,3,4-tetrahydroisoquinoline Hydrobromide (C9H11NOHBr) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 7-Hydroxy-1,2,3,4-tetrahydroisoquinoline Hydrobromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
