Chemical Structure
Description
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.
1-ethyl-1,2,3,4-tetrahydroisoquinoline hydrochloride (CAS 103861-49-0), molecular formula C11H15NHCl and molecular weight 197.71 g/mol, is a CATO reference standard with documented purity and traceability.
1-ethyl-1,2,3,4-tetrahydroisoquinoline hydrochloride (C11H15NHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-ethyl-1,2,3,4-tetrahydroisoquinoline hydrochloride 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.
