5-Methoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline CAS 56135-34-3

Description

The occurrence of 5-Methoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Methoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline (CAS 56135-34-3), molecular formula C11H15NO and molecular weight 177.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Methoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 177.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 5-Methoxy-2-methyl-1,2,3,4-tetrahydroisoquinoline 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.
