If you work with copper-bearing systems, you already know the quiet power of TTA. And yes, the chemistry is well-traveled, but the market isn’t standing still. Raw material volatility and tighter QA expectations are nudging buyers to rethink sourcing. Quick note for context: [cas 29385 43 1] is the Tolyltriazole you’re looking for—white, hygroscopic particles that punch well above their weight as corrosion inhibitors.
Tplyltriazole (TTA) from Tenger Chemical (origin: 3-2-501, North Courtyard, West District, Jiuli Courtyard, Yuhua District, Shijiazhuang City, Hebei, China) is offered in large, small, columnar, fine, or powdered forms. In practice, that flexibility matters for dust control and dosing accuracy. Actually, many customers say granules cut housekeeping time in half.
| Name | Tplyltriazole (Tolyltriazole, TTA) |
| CAS | [cas 29385 43 1] |
| Appearance | White to off-white particles/powder; easily hygroscopic |
| Purity (GC) | ≥99.0% (typical ≈99.5%) |
| Molecular formula / weight | C7H7N3; ≈133.15 g/mol |
| Melting point | ≈80–85°C (real-world may vary by isomer ratio) |
| Solubility | Slight in water; soluble in alcohols; highly soluble as sodium salt |
| pKa | ~8.4–8.6 |
| Moisture | ≤0.5% (typical) |
TTA forms an adsorbed protective film on copper and yellow metals. You’ll see it in: closed-loop HVAC and cooling towers, automotive antifreeze/engine coolants, metalworking fluids, cleaning compounds, and even some oil & gas blends. In fact, when paired with azoles’ friendly pH window and nitrite/MBT alternatives, performance tends to be stable and predictable.
Indicative test data (lab scale): copper corrosion ≤0.05 mg/cm² (336 h, ASTM D1384, 500–1000 ppm TTA). Field results do vary—make-up water, biocide selection, and shear matter more than people think.
Tenger offers particle sizing (fine powder → columnar granules), sodium-salt solutions (e.g., 50%), low-dust grades, and private-label packs. Standard packs: 25 kg bags or fiber drums; custom pallets on request. Store cool and dry—hygroscopicity is real.
| Vendor | Purity | Lead time | Compliance | Price (indic.) | Customization |
|---|---|---|---|---|---|
| Tenger Chemical | ≥99.0% (typ.) | 7–14 days | ISO 9001, REACH-ready, RoHS | Mid-range | Granule size, Na-salt, labels |
| Vendor A | ≥98.5% | 10–21 days | ISO only | Low–mid | Limited |
| Vendor B | ≥99.0% | 14–28 days | REACH, ISO | High | Good |
One HVAC OEM reported a 22% drop in copper ion release after switching to sodium TTA solution (same treat rate, better dispersion). A coolant blender told me—somewhat surprised—that switching from powder to columnar granules reduced foaming carryover during dissolution. That tracks with what we see in the lab on [cas 29385 43 1] dusting behavior.
Material is typically backed by ISO 9001 QMS; REACH/RoHS statements available on request. For proofing, ask for a COA with GC trace, moisture, ash, and color index. If your formulation is amine-rich, check compatibility—film persistence can shift slightly, though [cas 29385 43 1] is generally reliable across pH 7–10.
