Chemical Structure

(E)-3,5-dimethyl-4-(phenyldiazenyl)-1h-pyrazole CAS 1809102-39-3 chemical structure

Description

CATO supplies (E)-3,5-dimethyl-4-(phenyldiazenyl)-1h-pyrazole (CAS 1809102-39-3), a certified reference material (molecular formula C11H12N4, MW 200.24 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, (E)-3,5-dimethyl-4-(phenyldiazenyl)-1h-pyrazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 200.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), (E)-3,5-dimethyl-4-(phenyldiazenyl)-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.
