Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dimethoxy-2-((3-methylthiophen-2-yl)methyl)-1,2,3,4-tetrahydroisoquinoline.
6,7-Dimethoxy-2-((3-methylthiophen-2-yl)methyl)-1,2,3,4-tetrahydroisoquinoline (CAS 5259-43-8), molecular formula C17H21NO2S and molecular weight 303.42 g/mol, is a CATO reference standard with documented purity and traceability.
6,7-Dimethoxy-2-((3-methylthiophen-2-yl)methyl)-1,2,3,4-tetrahydroisoquinoline (C17H21NO2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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 6,7-Dimethoxy-2-((3-methylthiophen-2-yl)methyl)-1,2,3,4-tetrahydroisoquinoline 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.
