4-Bromo-1-(2,4-dichlorobenzyl)-1,2-dihydro-3h-pyrazol-3-imine CAS 895929-80-3

Description

The occurrence of 4-Bromo-1-(2,4-dichlorobenzyl)-1,2-dihydro-3h-pyrazol-3-imine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Bromo-1-(2,4-dichlorobenzyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 895929-80-3), a certified reference material (molecular formula C10H8BrCl2N3, MW 321.00 g/mol) for analytical method development and quality control.

Structurally, 4-Bromo-1-(2,4-dichlorobenzyl)-1,2-dihydro-3h-pyrazol-3-imine (C10H8BrCl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 321.00 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
