Chemical Structure
Description
The occurrence of 4-Chloro-1-((1,5-dimethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Chloro-1-((1,5-dimethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine (CAS 1006348-72-6) is a high-purity analytical reference standard with the molecular formula C9H12ClN5 and a molecular weight of 225.68 g/mol.
The molecular framework of 4-Chloro-1-((1,5-dimethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine (C9H12ClN5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 4-Chloro-1-((1,5-dimethyl-1h-pyrazol-4-yl)methyl)-1,2-dihydro-3h-pyrazol-3-imine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
