Tralopyril(CAS: 122454-29-9)

Tralopyril Used in non-metal Marine Antifouling paint. It is a metal-free antifouling agent for use in antifouling paints for ship hulls or other marine structures.this product has a broad spectrum of activity against hard-shelled and soft-bodied invertebrate animal fouling organisms.Because of its chemical and physical stability in coatings, the low water solubility and leachability, this product containing antifouling paints can often be specified for multiyear dry-docking intervals comparable to those achieved with copper-based products. General Information Common Name (ISO): Tralopyril IUPAC Name: 4-bromo-2-(4-chlorophenyl)-5-(trifluoromethyl)-1H-pyrrole-3-carbonitrile CAS Name:1H-Pyrrole-3-carbonitrile,4-bromo-2-(4-chlorophenyl)-5-(trifluorometthyl) CAS Registry No: 122454-29-9 Molecular Formula: C12H5BRCLF3N2 Molecular Weight: 349.5 Chemical And Physical Properties Appearance: White to off-white powder Purity (Chromatography): Minimum 95.0% w/w Water Content (Karl-Fisher Titration): Maximum 0.5% w/w Particle Size Distribution (Laser Diffraction): D50: 4.0-10.0μm; D99: maximum 25.0μm Oil Absorption Value (ISO 787-5): 28ml per 100g Density : 1.714 g/ml at 20°C Vapour Pressure:1.9x10-8 Pa at 20°C; 4.6x10-8Pa at 25°C Dissociation Constant: pKa=7.08 at 26°C PH: 5.16 at 22°C(0.19% w/v dispersion in distilled water) Shelf Life: If stored at ambient temperature, in the original sealed container, this product technical has an initial shelf life of five years. Advantages: Metal-free antifouling agent ·Low use concentrations provide cost-effective alternative to copper-based antifoulants ·Broad spectrum control of hard fouling organisms ·Long-lasting efficacy ·Effective in marine and freshwater environments ·Breaks down rapidly in the aquatic environment ·Does not induce galvanic corrosion, particularly suitable for metal hulls including aluminium ·Provides paint formulation flexibility including bright colours and improved colour retention, lower VOC as Well as water based paints
