Appearance: white crystalline flakes
Solubility: slightly soluble in water
Main indexes:
| Index | Tech grade |
| Purity by wt % | 99 min |
| Melting Point by ºC | 121~123 |
| Chlorides as Cl by wt % | 0.02 max |
| Color (Co-Pt) | 20 max |
| Heavy metals as Pb by wt % | 0.001 max |
| Arsenic by ppm | 2 max |
| Loss on drying by wt % | 0.1 max |
| Acid dissolving | Bright and clear liquid |
1. Commonly used as food preservative.
2. Raw material in the production of pesticide, dye, medicine, perfume, mordant, plasticizer.
3. Modifying agent for polyamide resin and alkyd resins.
4. Rust inhibitor of steel equipment and so.
We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
