Description
CATO manufactures 1-(3-Chlorophenyl)-3-(1-methyl-1H-pyrazol-3-yl)thiourea 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.
1-(3-Chlorophenyl)-3-(1-methyl-1H-pyrazol-3-yl)thiourea (CAS 903692-67-1) is a high-purity analytical reference standard with the molecular formula C11H11ClN4S and a molecular weight of 266.75 g/mol.
The molecular framework of 1-(3-Chlorophenyl)-3-(1-methyl-1H-pyrazol-3-yl)thiourea (C11H11ClN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
