Frequently Asked Questions
What is Thiourea?
Thiourea is supplied by Suraj Chemicals as white crystalline powder, practically odourless, identified by CAS number 62-56-6. It falls under our Specialty Chemicals range — see the Specification Sheet table above for its full characteristics.
What is Thiourea used for?
Typical applications include: Brightening agent in tin, silver and other metal electroplating/pickling baths; Intermediate for rubber-processing chemicals and photographic chemicals; Flotation reagent in gold-ore processing; Intermediate for agrochemicals and resin manufacture.
How should Thiourea be stored and handled?
A combustible solid like most organic powders, but not a notable fire hazard in itself -- store in a cool, dry place away from oxidisers. The real concern is toxicological: thiourea is a suspected carcinogen with goitrogenic (thyroid-affecting) activity -- avoid ingestion and prolonged dust inhalation, use gloves and good ventilation.
What packaging and pack sizes does Suraj Chemicals supply Thiourea in?
25/50 kg bags. Contact us if you need a different pack size, or a bulk/tanker quantity.
What is the shelf life of Thiourea?
Typically 3–6 months from date of manufacture when stored sealed, in a cool place away from direct sunlight and heat. Active content in hypochlorite / oxidising products declines gradually over time, so this is one to watch closely. As with any industrial chemical, request the current batch's manufacturing date and a fresh certificate of analysis for orders where exact remaining shelf life matters.
Is Thiourea hazardous to handle?
Yes — Thiourea is combustible and should be kept away from heat and ignition sources; toxic if mishandled and requires appropriate PPE; capable of releasing dust or vapour that is harmful if inhaled — use appropriate respiratory protection. Follow the storage and handling guidance above, use appropriate PPE, and download the Safety Data Sheet (SDS/MSDS) in the sidebar above for full GHS hazard, handling and PPE details.
Is a Specification Sheet, TDS or MSDS available for Thiourea?
Yes — a downloadable Specification Sheet (PDF) with full characteristics and specifications is available above, and a downloadable Safety Data Sheet (SDS/MSDS) for Thiourea is also available above.
