Overview
2,3-Dichlorophenol (2,3-DCP) is a chlorinated derivative of phenol, classified as an aromatic organic compound. It is primarily synthesized for industrial use as a chemical intermediate. Its dual chlorine substituents enhance reactivity, making it valuable in agrochemical and pharmaceutical synthesis. As a specialty chemical, 2,3-DCP is niche but critical in producing herbicides like dicamba. Its controlled handling is essential due to moderate toxicity and environmental persistence. B2B buyers typically source it from fine chemical manufacturers with strict quality controls.
Physical and Chemical Properties
2,3-Dichlorophenol exhibits typical phenolic properties, including weak acidity (pKa ~8.0) and solubility in polar organic solvents. Its crystalline form is stable under standard conditions but may darken upon prolonged light exposure. The compound’s chlorine atoms increase its lipophilicity compared to phenol, affecting its partitioning in environmental matrices. Its vapor pressure is low (0.03 mmHg at 25°C), reducing inhalation risks but requiring dust control during handling.
Main Applications
The primary use of 2,3-DCP is as a building block in synthesizing herbicides, notably dicamba, a broadleaf weed controller. It also serves in pharmaceutical intermediates for antiseptics and APIs (Active Pharmaceutical Ingredients). In research, it acts as a reagent for studying chlorophenol toxicity and degradation pathways. Niche applications include dyestuff synthesis, though demand here is limited compared to agrochemicals.
Safety and Storage
2,3-DCP requires careful handling due to its irritant properties. OSHA mandates PPE (gloves, goggles) and fume hoods for laboratory use. Spills should be neutralized with sodium carbonate and absorbed in inert material. Storage must avoid contact with oxidizers (risk of exothermic reactions) and moisture. Steel or polyethylene containers are typical. Shelf life exceeds two years if kept sealed and below 30°C.
B2B Procurement Guide
Buyers should prioritize suppliers with ISO 9001 certification and REACH compliance. Batch-specific COAs (Certificates of Analysis) must confirm purity (≥98%) and impurity profiles. Pricing varies by quantity and purity. Bulk orders (100+ kg) may secure 10-15% discounts. Logistics require hazardous chemical transport classification (UN 2020). Spot purchases are rare; forward contracts ensure supply stability.
