Chemical Structure
Description
The occurrence of 4-(2,4-Dichlorobenzoyl)-N',N'-dimethyl-1H-pyrrole-2-carbohydrazide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(2,4-Dichlorobenzoyl)-N',N'-dimethyl-1H-pyrrole-2-carbohydrazide (CAS 338977-16-5) is a high-purity analytical reference standard with the molecular formula C14H13Cl2N3O2 and a molecular weight of 326.18 g/mol.
The molecular framework of 4-(2,4-Dichlorobenzoyl)-N',N'-dimethyl-1H-pyrrole-2-carbohydrazide (C14H13Cl2N3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
