In the competitive landscape of chemical procurement, securing reliable access to high-quality raw materials is a cornerstone of successful B2B operations. 1,2-Dichlorobenzene (CAS 95-50-1), a versatile chemical used extensively in agrochemical, pharmaceutical, and dye industries, requires careful consideration during the purchasing process. This guide aims to equip procurement managers and R&D scientists with the knowledge to effectively buy 1,2-Dichlorobenzene, focusing on crucial quality metrics and supplier selection.

At its core, 1,2-Dichlorobenzene is a colorless transparent liquid with a molecular formula of C6H4Cl2. Its primary value lies in its purity and consistency. For most industrial applications, particularly as an intermediate in synthesis, a purity level of ≥99.0% is standard. This high degree of purity minimizes the risk of side reactions and ensures the integrity of the final product, whether it’s a pesticide, a pharmaceutical compound, or a specialized dye.

Beyond overall purity, specific parameters are critical indicators of quality. Low water content, typically ≤0.03%, is essential, as moisture can interfere with many organic reactions. Similarly, a low acid value and controlled density (around 1.300-1.330 at 20℃) are vital for ensuring predictable reaction kinetics and process efficiency. When you intend to purchase 1,2-Dichlorobenzene, always request a detailed Certificate of Analysis (CoA) that specifies these parameters.

The selection of a supplier is as critical as the product specifications themselves. As a buyer, you should prioritize manufacturers and suppliers who can guarantee a stable and consistent supply chain. This reliability is crucial for maintaining uninterrupted production cycles. Furthermore, understanding the supplier's manufacturing capabilities, adherence to quality management systems, and logistical proficiency is important. For businesses operating globally, identifying suppliers with a strong presence and efficient export capabilities, such as those in China, can be advantageous for both pricing and availability.

When comparing options to buy 1,2-Dichlorobenzene, consider the packaging and shelf life. Standard packaging, such as 250kg drums, is common. The typical shelf life of 12 months means that proper inventory management is necessary to ensure the chemical remains within its efficacy period.

In essence, procuring 1,2-Dichlorobenzene demands a diligent approach. Focus on verifying purity and other key specifications through detailed CoAs. Partner with reliable manufacturers and suppliers who offer competitive pricing, consistent supply, and robust quality assurance. By prioritizing these aspects, procurement professionals can secure the high-quality 1,2-Dichlorobenzene necessary to drive innovation and success in their respective industries.
