4-Chloro-1-((1-ethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine CAS 1004452-02-1

Description

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.

4-Chloro-1-((1-ethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 1004452-02-1) is a high-purity analytical reference standard with the molecular formula C9H12ClN5 and a molecular weight of 225.68 g/mol.

4-Chloro-1-((1-ethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine (C9H12ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
