Chemical Structure
Basic Info
As a chemical that falls under specialized transport and hazardous material classifications, regulatory safety and compliance are paramount. Zhishang Chem provides a secure and legally transparent supply chain back-up:
- ISO 9001:2015 Registered:Manufactured under strict, standard-driven quality monitoring systems to guarantee reliable batch-to-batch uniformity.
- UN-Compliant Hazardous Cargo Packing:Our packaging holds international UN certification for Class 4.2 (Substances liable to spontaneous combustion) or Class 4.1, depending on customized regional freight requirements, ensuring smooth customs clearance.
- Eco-Textile Standard Alignment:Free from restricted heavy metals and banned aromatic amines, ensuring your downstream textile products seamlessly pass strict OEKO-TEX Standard 100 audits.
Product Packaging
Our high-purity Thiourea Dioxide (CAS 1758-73-2) serves as an indispensable active agent across multiple large-scale industrial processing sectors:
- Textile Vat Dyeing & Reduction Clearing:Functions as an exceptional textile vat dyeing chemical. It provides deep, consistent reduction of vat dyes and sulfur dyes on cotton and blended fabrics, and efficiently removes unfixed surface dyes during reduction clearing without damaging fabric fibers.
- Paper De-inking & Pulp Bleaching:Extensively utilized in recycling facilities to bleach wastepaper pulp and remove graphic inks, significantly enhancing the brightness of recycled paper fibers while lowering wastewater chemical oxygen demand (COD).
- Organic Synthesis & Polymerization:Acts as a specialized catalyst or reducing agent in photographic emulsions, synthetic leather production, and the manufacturing of acrylic resins.
- Processing Tip:Thiourea Dioxide displays unique properties: it is highly stable at room temperature but releases its full reduction potential when heated above 60°C in an alkaline medium (pH 9-10). Always ensure thorough mixing in water before raising the system temperature.
FAQ
A: Our standard commercial configuration for formamidine sulfinic acid bulk orders is 25kg or 50kg tightly sealed plastic woven bags with double inner PE liners, or 500kg/1000kg UN-approved container bags. We also include specialized desiccants inside the master packaging to guarantee absolute dryness and prevent product caking during long maritime voyages.
A: It must be stored in a cool, dry, well-ventilated warehouse strictly below 30°C (86°F). Keep containers tightly sealed and completely isolated from direct sunlight, heat sources, moisture, and incompatible compounds such as oxidizing agents, acids, or flammable materials.

Self-Inspection & Quality Control (Purity & Stability Standards)
Because Thiourea Dioxide can degrade if exposed to moisture or improper processing temperatures, Zhishang Chem implements an aggressive self-inspection protocol for every single manufacturing batch before it enters our export warehouses:
- Thiourea Dioxide Content (Assay):≥ 99.0% Minimum
- Residual Thiourea:≤ 0.1%
- Moisture Content:≤ 0.05% (Crucial for preventing self-heating during long-term maritime transit).
- Iron (Fe) Content:≤ 10 ppm
- Traceability Promise: We completely eliminate product uncertainty. Every delivery includes an authentic Certificate of Analysis (COA) directly from our analytical lab, ensuring the moisture and purity parameters perfectly match your technical processing sheets.
Manufacturer of Thiourea Dioxide
1. For products ≤50kg, we recommend using express delivery, which is usually called DDU service (discounted, convenient).
2. For products ≤500kg, we generally recommend air freight, which is usually called FOB, CFR or CIF service (fast and efficient).
3. For products >500kg, we generally recommend shipping by sea, which is usually called FOB, CFR or CIF service (economical, safe).
4. For high-value products, please choose air or express to ensure the safety of product transportation.
