2,3,5,6-Tetrachloroterephthalonitrile is a perchloro aromatic dinitrile synthesis intermediate — a building block used in the manufacture of fungicide-active and pigment intermediates. Identity: CAS 1897-41-2.
What it is
2,3,5,6-Tetrachloroterephthalonitrile (CAS 1897-41-2, C8Cl4N2) is a perchloro aromatic dinitrile sold as a synthesis intermediate — a defined building block that downstream manufacturers convert into finished products. Confirm regulatory status for your market and end use.
Role in synthesis
The dinitrile and ring chlorines are reactive handles for fungicide and pigment synthesis. The substitution pattern (isomer) is part of the identity — confirm the CAS to be sure the isomer matches your route, because position isomers react differently and lead to different products.
What it is used to make
It is a building block toward fungicide-active and pigment intermediates. RawSource supplies the intermediate; the downstream synthesis, product registration and any application or efficacy are the responsibility of the manufacturer that uses it.
Forms, grades and handling
Supplied to a defined assay with a Certificate of Analysis (CoA) per lot; define the assay and key impurity limits your route needs. Several halo-aromatic intermediates are hazardous and some are regulated — confirm regulatory status and handling for your jurisdiction, and always consult the current Safety Data Sheet (SDS). Typical values are not a guaranteed specification; the CoA governs.
Bulk and custom-quantity supply
RawSource sources 2,3,5,6-Tetrachloroterephthalonitrile direct from producers in bulk and custom quantities, with CoA, TDS and SDS per lot. Tell us the assay and impurity limits and your sample/pilot/production quantity, and we will quote it and confirm supply continuity. See the full range in the intermediates guide.
