3,4-Dichlorobenzonitrile is a dichloro-benzonitrile synthesis intermediate — a building block used in the manufacture of agrochemical and pharmaceutical intermediates. Identity: CAS 6574-99-8.
What it is
3,4-Dichlorobenzonitrile (CAS 6574-99-8, C7H3Cl2N) is a dichloro-benzonitrile sold as a synthesis intermediate — a defined building block that downstream manufacturers convert into finished products. The 3,4-isomer is distinct from other dichlorobenzonitriles.
Role in synthesis
As a nitrile, the cyano group can be hydrolyzed to the corresponding acid or amide, or reduced to a primary amine, while the ring halogens are reactive sites for nucleophilic aromatic substitution. 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 agrochemical and pharmaceutical 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 3,4-Dichlorobenzonitrile 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.
