CAS 17766-26-6 corresponds to 1,3,5-triazine-2,4,6 (1H, 3H, 5H) – trithioketone trisodium salt (commonly known as trisodium thiocyanate or TMT-15 active ingredient or TMT-53%), which is an efficient organic sulfur heavy metal scavenger with the molecular formula C ∝ N ∝ Na ∝ S ∝. It is mainly used in wastewater treatment to remove heavy metal ions such as mercury, lead, and cadmium.

Core Basic Information
-Chinese name: 1,3,5-triazine-2,4,6 (1H, 3H, 5H) – trithioketone trisodium salt (also known as trisodium thiocyanate, trisodium trimercaptotriazine trisodium salt)
-English name: 1,3,5-Tiazine-2,4,6-triphiol trisodium salt/Trithiocyanuric Acid Trisodium salt
-Molecular formula: C ∝ N ∝ Na ∝ S ∝
-Molecular weight: approximately 243.22
-EINECS number: 241-749-5
-Common forms: white to pale yellow crystalline powder, or pale yellow aqueous solution with a solid content of 15%/55%
-Main use: Industrial wastewater heavy metal capture agent (especially suitable for removal of complex heavy metals)

Key Features and Applications
1. Mechanism of action: The three thiol groups (- SH) in the molecule form stable and insoluble chelating precipitates with heavy metal ions (such as Hg ² ⁺, Pb ² ⁺, Cd ² ⁺, Ag ⁺, Cu ² ⁺, etc.), which remain effective even in the presence of high salt or chelating agents (such as EDTA).
2. Advantages and characteristics: low dosage, high efficiency, no secondary pollution, large sedimentation flocs that are easy to dehydrate, low toxicity, and do not produce odor.
3. Applicable scenarios: heavy metal wastewater treatment in industries such as electroplating, petrochemicals, metallurgy, battery manufacturing, and waste incineration; Can be used directly within the pH range of 6-9.
4. Safety warning: Irritating to eyes (R36/H319). In case of contact with eyes, rinse immediately with plenty of water and seek medical attention; Storage should be dry and cool, avoiding direct contact.

Precautions
Commercial products often appear under the trade name “TMT-15″, usually in an aqueous solution containing 15% of the ingredient; High purity reagents are mostly crystalline powders. Its chemical properties are stable, but specific operations must follow MSDS and safety regulations.
