2,3,5,6-Tetrafluoroterephthalonitrile

2,3,5,6-Tetrafluoroterephthalonitrile is described as a white to off-white crystalline solid, offered by Zhejiang Huaji Biotechnology Co.,Ltd at pharmaceutical grade under in-house standards; the CAS number listed for this entry (1835-49-0) recurs elsewhere in the catalog attached to a different fluorinated benzene compound, so it should be treated with caution. It is distributed across North America, Central/South America, Western and Eastern Europe, Australasia, Asia, the Middle East, and Africa, though the supplier does not manufacture it directly.
