The pharmaceutical industry operates under the most stringent quality standards, where the purity and consistency of every chemical component are non-negotiable. For those involved in synthesizing Active Pharmaceutical Ingredients (APIs) and complex drug molecules, understanding the precise specifications of key intermediates like Tetrachloroterephthalonitrile (CAS 1897-41-2) is fundamental. This compound serves as a critical building block, and its quality directly impacts the safety and efficacy of life-saving medications.

Tetrachloroterephthalonitrile is typically supplied as a white crystalline powder. This physical form is advantageous for handling, storage, and integration into various reaction processes commonly employed in pharmaceutical manufacturing. The chemical name, 2,3,5,6-tetrachlorobenzene-1,4-dicarbonitrile, along with its molecular formula C8Cl4N2, provides chemists with the essential identifiers needed for formulation and process design. A high assay, specifically ≥99%, is a critical specification that pharmaceutical manufacturers demand. This level of purity ensures that the intermediate will react predictably, minimizing the formation of unwanted isomers or byproducts that could complicate purification steps or compromise the final drug product.

The melting point of Tetrachloroterephthalonitrile, typically between 308-312°C, indicates its thermal stability. This property is vital for processes that may involve elevated temperatures, ensuring the integrity of the molecule throughout synthesis. Furthermore, understanding its solubility characteristics – generally soluble in organic solvents like acetone and chloroform but insoluble in water – guides chemists in selecting appropriate reaction media and work-up procedures.

When considering a Tetrachloroterephthalonitrile supplier, it is crucial to seek out manufacturers that can provide a detailed Certificate of Analysis (CoA) with each batch. This document should clearly state the purity, presence of any impurities, and other relevant physical and chemical properties. Reliability in supply is equally important; pharmaceutical production schedules are often tight, and any disruption due to inconsistent intermediate availability can be costly.

For procurement managers and R&D scientists in the pharmaceutical sector, sourcing competitively priced, high-quality Tetrachloroterephthalonitrile from a trusted manufacturer in China, such as NINGBO INNO PHARMCHEM CO.,LTD., offers a strategic advantage.
