Isophorone

Isophorone (IPHO) is used in many end markets such as agrochemicals, fine chemistry, coating, inks, epoxy systems, isocyanates.

IPHO, an unsaturated cyclic ketone, is a raw material in many chemical synthesis: IPDA/IPDI (isophorone diamine / isophorone diisocyanate), PCMX (antimicrobial derivatives of 3,5-xylenol), Trimethylcyclohexanone…

IPHO is also used as a solvent, especially in coatings, inks and agrochemicals.
