For professionals in the chemical industry, a thorough understanding of key intermediates is crucial for successful product development and manufacturing. 2,6-Dichlorotoluene (CAS 118-69-4) is one such compound, valued for its specific chemical characteristics and its role as a precursor in various synthetic processes. This article explores its fundamental properties, common synthesis routes, and the benefits of sourcing it from established Chinese suppliers.

2,6-Dichlorotoluene, with the molecular formula C7H6Cl2, is an aromatic compound characterized by a toluene ring substituted with two chlorine atoms at the ortho positions relative to the methyl group. Its CAS number is 118-69-4, a critical identifier for procurement and regulatory purposes. Understanding its physical and chemical properties is the first step for any formulator or researcher planning its use.

Key Chemical and Physical Properties

The appearance of 2,6-Dichlorotoluene is typically described as a colorless liquid, though slight yellowing can occur. It has a melting point of approximately 2°C and a boiling point in the range of 196-203°C at atmospheric pressure. Its density is around 1.254 g/mL at 25°C. While it exhibits low solubility in water (around 24 mg/L at 20°C), it readily dissolves in common organic solvents such as benzene and toluene. The flash point, typically around 82°C, is an important safety consideration during handling and storage.

Synthesis Pathways

The preparation of 2,6-Dichlorotoluene can be achieved through several chemical routes. One common method involves the Sandmeyer reaction on 2-amino-6-chlorotoluene. Other pathways include ring chlorination and desulfonylation of p-toluene sulfonyl chloride, or chlorination and dealkylation processes involving tert-butyltoluene derivatives. For industrial-scale production, manufacturers focus on efficient and cost-effective synthesis methods to ensure product availability and competitive pricing.

Sourcing from China: A Strategic Advantage

When it comes to sourcing specialized chemical intermediates like 2,6-Dichlorotoluene, manufacturers and researchers often turn to China due to its robust chemical industry. Partnering with a reputable China manufacturer or supplier of 2,6-Dichlorotoluene offers several benefits. These include access to high-purity products (often exceeding 99%), competitive pricing structures, and a more stable supply chain. Companies looking to buy 2,6-Dichlorotoluene can leverage these advantages to streamline their procurement processes and reduce overall production costs.
