Chemical Structure

3-Ethyl-2-methyl-7-nitro-1,2,3,4-tetrahydroisoquinoline CAS 768340-96-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Ethyl-2-methyl-7-nitro-1,2,3,4-tetrahydroisoquinoline.

3-Ethyl-2-methyl-7-nitro-1,2,3,4-tetrahydroisoquinoline (CAS 768340-96-1), molecular formula C12H16N2O2 and molecular weight 220.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Ethyl-2-methyl-7-nitro-1,2,3,4-tetrahydroisoquinoline (C12H16N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 3-Ethyl-2-methyl-7-nitro-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.
