For any B2B chemical transaction, a thorough understanding of product specifications is non-negotiable. This is particularly true for intermediates like 2,6-Dichloroanisole (CAS 1984-65-2), which serve as critical building blocks in complex synthetic pathways. Procurement managers, R&D scientists, and formulation specialists must be well-versed in the key parameters that define the quality and suitability of this compound. Partnering with a reliable manufacturer that consistently meets these specifications is paramount for successful operations.

The most immediately observable characteristic of 2,6-Dichloroanisole is its appearance. Typically described as a yellow transparent liquid, this visual cue provides an initial indication of the product's state and potential purity. Deviations from this description could signal issues with handling, storage, or the manufacturing process itself.

Crucially, the assay, or purity level, is a defining specification. For 2,6-Dichloroanisole, an assay of ≥98.0% is commonly required. This high purity ensures that the compound will perform as expected in sensitive reactions, minimizing the introduction of unwanted byproducts that could complicate downstream processes or compromise the final product's integrity. Buyers looking to buy this chemical should always verify the assay from their prospective supplier.

Moisture content is another critical parameter, especially for intermediates used in moisture-sensitive reactions common in organic synthesis. A specification of ≤0.2% moisture content is standard and vital for maintaining reaction efficiency and preventing degradation of the compound or other reagents. This is why sourcing from manufacturers with stringent drying and packaging protocols is important.

Beyond purity and moisture, a range of physical and chemical properties are provided by reputable suppliers, offering valuable data for process design and optimization. These include:

  • Density: Approximately 1.29 g/cm³, important for volume-to-mass conversions in calculations.
  • Melting point: 10-11°C, indicating its liquid state under typical laboratory and industrial conditions.
  • Boiling point: Around 117°C, relevant for distillation and separation processes.
  • Flash point: 91°C, a key safety parameter for handling and storage, indicating the lowest temperature at which vapors can ignite.
  • Index of Refraction: 1.542-1.544, useful for identification and quality verification.

When considering a purchase, especially from a supplier in China, it is advisable to request a detailed specification sheet or CoA. This document serves as confirmation of the product's quality and compliance with industry standards. Many manufacturers offer standard packaging in 200 kg drums, but flexibility for custom packaging may also be available. Understanding these specifications empowers buyers to make informed decisions, secure the right intermediate, and ensure the success of their synthesis projects. Always inquire about the price and availability when requesting detailed product information.
