Amine intermediates
Anilines, toluidines, anisidines and phenylenediamines: the diazo and coupling components behind most azo dyes.
Where they are used

Check the spelling, try part of the name, or search by CAS number. If it is a product we do not list yet, our team can check availability for you.
Not sure which product you need?
Start from whatever you already know. Our technical team works in diazotisation, coupling and sulfonation every day and can point you to the right grade.
You know the chemical name
Type the name or CAS number into the search above. Short forms like "o-toluidine" or "24 dinitro" work too.
You know the shade you need
Reds, yellows and bordeaux pigments start with pigment intermediates. Most azo dyes start with amine intermediates.
You know the reaction step
Process chemicals cover sulfonation, diazotisation and alkylation. Benzenes and nitro compounds are the starting materials.
You are switching suppliers
Send the specification you work to. We confirm whether we can match it and send a sample with its test data.
