7-bromopyrazolo[5,1-a]isoquinoline CAS 2766427-66-9

Description

Compared with other compounds in its class, the molecular weight of 259.19 g/mol gives 7-bromopyrazolo[5,1-a]isoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-bromopyrazolo[5,1-a]isoquinoline (CAS 2766427-66-9), molecular formula C11H19BrN2 and molecular weight 259.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-bromopyrazolo[5,1-a]isoquinoline (C11H19BrN2) is characterized by a nitrile group, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 7-bromopyrazolo[5,1-a]isoquinoline 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.
