Chlorothalonil TC

Description

1. Product Overview
Chlorothalonil TC is a high-purity, broad-spectrum, organochlorine fungicidal active ingredient used extensively in the formulation of crop protection products. Its primary industrial application is the manufacturing of suspension concentrates (SCs), wettable powders (WPs), and water-dispersible granules (WGs) for controlling fungal diseases in high-value row crops, vegetables, and turf. The key value proposition lies in its multi-site mode of action, which delivers exceptional resistance management—making it a strategically critical asset for global agrochemical manufacturers seeking to prolong the efficacy of integrated pest management (IPM) programs and safeguard yield reliability.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Tetrachloroisophthalonitrile (98%–99% typical assay); multi-site contact fungicide

• Purity Level: ≥ 98.0% min. (HPLC); technical grade (TC) suitable for downstream formulation

• Physical Characteristics: Off-white to light gray fine crystalline powder; low dusting; characteristic mild odor

• Particle Size: 98% passing through 325 mesh (≤ 44 µm) for rapid dispersion

• Bulk Density: Tapped 0.60–0.80 g/cm³; free-flowing properties optimized for blending

• Packaging Options: 25 kg net multi-wall kraft paper bags with PE liner; 500 kg & 1000 kg FIBCs; custom to buyer specification

• Shelf Life: 36 months when stored in original unopened containers under dry, ambient conditions (≤ 35°C)

3. Core Industrial Applications

• Primary Industries: Large-scale agrochemical formulation, specialty crop protection, seed treatment, and turf & ornamental production.

• Specific Use Cases:

  • Formulation into SCs for peanut leaf spot, potato early blight, and tomato late blight control.

  • Blending with systemic fungicides (e.g., azoxystrobin, mancozeb) to create synergistic resistance-management blends.

  • Industrial production of protective sprays for high-frequency application in humid tropical agriculture.

• Performance Advantage vs. Alternatives: Unlike single-site fungicides (e.g., strobilurins), Chlorothalonil TC’s multi-site activity effectively eliminates risk of target-site resistance—prolonging product lifecycles for formulators. It provides superior rainfastness (adheres within 1–2 hours post-application) and longer residual leaf coverage compared to copper-based or sulfur-based protectants, reducing total application frequency and per-hectare cost for growers.

4. Competitive Advantages

• Quality Consistency: ISO 9001:2015-certified production with batch-to-batch purity variance < 0.5%; full COA including impurity profiling (HPLC, GC-MS) for each lot.

• Supply Reliability: Vertically integrated manufacturing with >15,000 MT annual capacity; buffer stock maintained in three regional hubs (Asia, Europe, Americas).

• Logistics Capability: Dangerous goods (Class 9, UN3077) certified packaging; temperature-controlled container options; door-to-door track-and-trace.

• Price Competitiveness: Direct-from-manufacturer pricing with volume-based tiering; no hidden surcharges for re-testing or documentation.

• Sustainability & Technical Support: Low-VOC residual process; full SDS and REACH/EPA compliance dossier included. Dedicated technical team provides formulation optimization support (compatibility screening, wetting agent matching).

5. Commercial & Supply Information

• Minimum Order Quantity (MOQ): 20 MT (one full container load equivalent)

• Loading Capacity: 20 MT per 20-foot dry container (palletized: 22 standard pallets; bulk bags: 20 FIBCs of 1,000 kg each)
