Description

Compared with other compounds in its class, the molecular weight of 267.12 g/mol gives 1-(5-Bromo-2-methoxyphenyl)-5-methyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(5-Bromo-2-methoxyphenyl)-5-methyl-1H-pyrazole (CAS 1395896-56-6), molecular formula C11H11BrN2O and molecular weight 267.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(5-Bromo-2-methoxyphenyl)-5-methyl-1H-pyrazole (C11H11BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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 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.
