What is the specification, CAS number and packing of thiourea dioxide?

Direct answer

Thiourea dioxide has CAS number 1758-73-2, formula CH₄N₂O₂S and molecular weight 108.12. Our industrial grade assays 99% minimum active content, and every batch is fully tested before dispatch with a COA issued.

Typical specification

Packing

• 25 kg or 80 kg kraft-paper or plastic woven bags
• 50 kg fibre drums
• 500 kg jumbo bags

Custom packing specifications can be arranged.

Batch consistency and testing

Every batch completes the full specification test before dispatch, covering assay, moisture, residual thiourea, ash, iron content and a dedicated safety performance test. Non-conforming batches are not released. Every lot is traceable by batch number and a retention sample is kept.

Common purchasing questions

• Is this the same as "thiourea dioxide 48% / 70% / 90%"? Those are grades with different active content; dosage must be converted on the actual assay.
• Can I get a sample? New customers receive a standard free 200 g sample with TDS, SDS, COA and the packing specification.
