Chlorobenzonitrile

Description

1. Product Overview

Chlorobenzonitrile (mixed isomer, primarily ortho- and para- ) is a high-purity aromatic nitrile intermediate essential for the synthesis of advanced agrochemicals, pharmaceuticals, and high-performance specialty dyes. Its primary industrial use lies in enabling selective chlorination and cyanation reactions that are critical for active pharmaceutical ingredients (APIs) and systemic crop protection compounds. The key value proposition is exceptional batch-to-batch isomer consistency and low residual solvent profile, which directly reduces downstream purification costs for formulators. Strategically, with tightening global supplies of chlorinated aromatics, securing a reliable source of Chlorobenzonitrile mitigates raw material risk for multinational chemical manufacturers.

2. Key Specifications & Technical Characteristics

• Chemical composition: Chlorobenzonitrile (ClC₆H₄CN) – ≥99.5% total isomer purity; typical isomer ratio: o-chloro 45–55% / p-chloro 45–55% (custom ratios available)

• Purity / grade: Technical grade (industrial synthesis) and high-purity grade (≥99.9% for pharmaceutical intermediates)

• Physical characteristics: White to off-white crystalline powder; melting point 43–46°C (para isomer) / 46–48°C (ortho); bulk density 0.55–0.65 g/cm³; average particle size D50: 150–300 µm

• Packaging options: 25 kg multi-layer kraft-aluminum foil bags; 500 kg FIBC bulk bags; 200 L UN-certified fiber drums with desiccant liner

• Shelf life: 24 months when stored below 30°C in original unopened packaging, protected from moisture and strong oxidizers

3. Core Industrial Applications

• Agrochemicals (primary industry): Synthesis of substituted benzamide insecticides (e.g., chlorantraniliprole intermediates) and herbicidal sulfonylureas – our Chlorobenzonitrile delivers higher nitrile conversion rates (≥97%) than chlorinated benzonitrile alternatives, reducing catalyst loading by 12–15%.

• Pharmaceuticals: Intermediate for antifungal agents (e.g., butoconazole) and antipsychotic APIs – the low residual palladium and heavy metal content (each <5 ppm) eliminates a polishing purification step, saving $180–250 per kilo of final API.

• Specialty dyes & pigments: Production of phthalocyanine and azo condensation dyes – superior isomer purity prevents off-color side reactions, increasing color yield per batch by 8–10% compared to commodity-grade nitriles.

• Performance polymers: Monomer for poly(arylene ether nitriles) used in high-temperature composites – the low moisture pick-up (<0.1% after 24h at 50% RH) ensures stable polymerization kinetics.

4. Competitive Advantages

• Quality consistency: SPC-monitored production with inter-laboratory validation (ISO 17025) – typical isomer ratio Cpk >1.33, guaranteeing identical performance across multi-year contracts.

• Supply reliability: Dual-source manufacturing (Asia and Europe) with 4,000 MT annual nameplate capacity and 90-day safety stock held in Rotterdam and Houston.

• Logistics capability: UN 3437 (Class 6.1, PG II) certified shipping; door-to-door temperature-controlled containers available for tropical climates.

• Price competitiveness: Direct-from-reactor pricing, removing 2–3 distribution layers – average 14% lower landed cost than European spot market equivalents for MT-scale orders.

• Sustainability & support: Toluene-free cyanation process (reduces VOC emissions by 40%); full SDS, REACH and TSCA compliance pack, plus custom impurity fingerprinting within 5 working days.
