(E)-1,3-dimethyl-4-(2-nitrovinyl)-5-phenoxy-1H-pyrazole CAS 477710-91-1

Description

The occurrence of (E)-1,3-dimethyl-4-(2-nitrovinyl)-5-phenoxy-1H-pyrazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-1,3-dimethyl-4-(2-nitrovinyl)-5-phenoxy-1H-pyrazole (CAS 477710-91-1), a certified reference material (molecular formula C13H13N3O3, MW 259.26 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (E)-1,3-dimethyl-4-(2-nitrovinyl)-5-phenoxy-1H-pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), (E)-1,3-dimethyl-4-(2-nitrovinyl)-5-phenoxy-1H-pyrazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
