Chemical Structure

N-1H-Pyrazol-3-ylthiourea CAS 758715-91-2 chemical structure

Description

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

N-1H-Pyrazol-3-ylthiourea (CAS 758715-91-2), molecular formula C4H6N4S and molecular weight 142.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-1H-Pyrazol-3-ylthiourea (C4H6N4S) is characterized by a nitrile group, sulfur-containing functionality. 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 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).

CATO manufactures N-1H-Pyrazol-3-ylthiourea 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.
