Thiourea Applications
Pharmaceutical and Agrochemical Intermediates
Thiourea serves as a starting material and intermediate in the synthesis of pharmaceuticals, pesticides and other organic chemicals. For these buyers, assay and impurity specifications are important parts of raw-material qualification.
Agriculture and Fertilizer Applications
Thiourea is used in fertilizer-related applications and crop-management treatments. We support agricultural buyers with bulk raw-material supply and samples for quality and application testing.
Metal Cleaning and Surface Treatment
Thiourea is used in metal-cleaning formulations, including silver-polishing and tarnish-removal products. It also has applications in electroplating and related surface-treatment processes.
Metallurgy and Mineral Processing
Metallurgical applications include gold and silver ore leaching and copper refining. Thiourea acts as a process reagent in these operations, serving customers purchasing chemicals for metal extraction and treatment.
Packaging, Delivery and Trade Terms
Our standard thiourea packaging is a 25 kg woven bag with a plastic inner liner. Choose palletized or non-palletized loading to match your receiving and handling requirements.
