Cas 29385 43 1 is a key solution in the chemical industry industry, specifically within fine chemicals and Metal preservatives. This article explores how Hebei Tenger Chemical Technology Co., Ltd. supports professionals with durable, high-performance products, and explains why this product is an ideal choice for businesses in these sectors.

Cas 29385 43 1 is the widely used corrosion inhibitor Tolyltriazole (TTA), a mixture of 4- and 5-methyl-1H-benzotriazole isomers. With molecular formula C7H7N3 (also written as c7h7n3) and high activity on copper and copper alloys, TTA forms a compact, persistent chemisorbed film that drastically slows anodic and cathodic reactions. Also known as methyl benzotriazole or .methyl 1h benzotriazole in some catalogs, it delivers reliable protection in water-treatment, coolants, metalworking fluids, and multi-metal preservation systems. Typical specs include assay ≥99%, melting range about 79–85°C, low water solubility (enhanced as sodium salt), and excellent solubility in alcohols and glycols.
Hebei Tenger Chemical Technology Co., Ltd. manufactures and supplies Tolyltriazole as flakes/powder and as liquid salts for easier dosing, backed by COA/SDS documentation and batch traceability. In a closed-loop cooling case, customers dosing 3–10 ppm TTA typically observe markedly lower copper ion release and reduced tarnish versus untreated systems—supporting longer asset life and fewer unscheduled interventions. The company’s controlled isomer ratio, low impurity profile, and consistent particle size aid predictable dissolution and performance in industrial blending and on-site make-up.
In Metal preservatives, Cas 29385 43 1 (Tolyltriazole) is a go-to choice for protecting copper, brass, bronze, and multi-metal assemblies. It’s widely applied in recirculating cooling water, HVAC/chiller systems, industrial and automotive antifreeze (glycol-based coolants), metalworking fluids, vapor-phase inhibitor formulations, and rinse/cleaning steps that risk flash corrosion. TTA is favored for its low-dose effectiveness, thermal stability, and synergy with nitrite, molybdate, and azole-compatible inhibitors, making it adaptable across diverse operating conditions.
Total cost of ownership with Cas 29385 43 1 is attractive because efficacy is achieved at low concentrations, extending equipment life and reducing maintenance frequency. Users often report fewer episodes of staining/tarnish on copper components, lower copper pickup in system analyses, and improved appearance retention on brass fittings. When paired with sound water chemistry control (e.g., pH management and oxidant compatibility), TTA helps stabilize system conditions, which translates into reduced downtime and consumable usage.
Sustainability and regulatory stewardship are reshaping metal preservation. Stakeholders aim for lower environmental footprints, better effluent management, and safer handling. Azole-based inhibitors like Tolyltriazole remain central in high-performance systems, while producers and formulators emphasize optimized dosing, closed-loop usage, and efficient capture/treatment strategies where wastewater limits apply. Market growth is driven by infrastructure upgrades, data center cooling, and electrification trends—all demanding reliable corrosion control with predictable life-cycle costs.
Cas 29385 43 1—Tolyltriazole, also called methyl benzotriazole—delivers dependable, low-dose protection across fine chemicals and Metal preservatives, safeguarding copper and mixed-metal systems in demanding environments. Backed by Hebei Tenger Chemical Technology Co., Ltd.’s consistent quality, supply reliability, and technical support, it helps B2B operators lower TCO and extend asset life.
