Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(1-Phenyl-3-p-tolyl-1H-pyrazol-5-yl)thiourea.
CATO supplies 1-(1-Phenyl-3-p-tolyl-1H-pyrazol-5-yl)thiourea (CAS 851052-50-1), a certified reference material (molecular formula C17H16N4S, MW 308.40 g/mol) for analytical method development and quality control.
The molecular framework of 1-(1-Phenyl-3-p-tolyl-1H-pyrazol-5-yl)thiourea (C17H16N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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), 1-(1-Phenyl-3-p-tolyl-1H-pyrazol-5-yl)thiourea 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.
