7-Methoxy-6-methyl-2-tosyl-1,2,3,4-tetrahydroisoquinoline-5,8-dione CAS 113361-38-9

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.

7-Methoxy-6-methyl-2-tosyl-1,2,3,4-tetrahydroisoquinoline-5,8-dione (CAS 113361-38-9) is a high-purity analytical reference standard with the molecular formula C18H19NO5S and a molecular weight of 361.41 g/mol.

The molecular framework of 7-Methoxy-6-methyl-2-tosyl-1,2,3,4-tetrahydroisoquinoline-5,8-dione (C18H19NO5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 7-Methoxy-6-methyl-2-tosyl-1,2,3,4-tetrahydroisoquinoline-5,8-dione 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.
