Chemical Structure

(6S,8R)-6-(5-Bromopyridin-2-yl)-8-methyl-7-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinoline CAS 2142634-01-1 chemical structure

Description

The occurrence of (6S,8R)-6-(5-Bromopyridin-2-yl)-8-methyl-7-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(6S,8R)-6-(5-Bromopyridin-2-yl)-8-methyl-7-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinoline (CAS 2142634-01-1), molecular formula C18H16BrF3N4 and molecular weight 425.25 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (6S,8R)-6-(5-Bromopyridin-2-yl)-8-methyl-7-(2,2,2-trifluoroethyl)-6,7,8,9-tetrahydro-3H-pyrazolo[4,3-f]isoquinoline (C18H16BrF3N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
