Isophthalic acid imagwiritsidwa ntchito makamaka popanga unsaturated polyester resin, PET copolymer mtengo chala ndi alkyd resin. Komanso, asidi isophthalic monga zopangira angagwiritsidwenso ntchito pokonzekera polyisophthalic asidi allyl ester (DAIP) utomoni, amene chimagwiritsidwa ntchito popanga mwatsatanetsatane ndi zovuta mkulu-kutentha insulating mbali ndi impregnated laminates. Kukonzekera kwa diethyl isophthalate (DEIP) ngati mankhwala apadera a Chemicalbook popanga toluene diisocyanate; Kukonzekera kwa polybenzimidazole ntchito monga zomatira kwa zotayidwa aloyi, zitsulo zosapanga dzimbiri ndi zipangizo zina zitsulo, zitsulo zisa dongosolo, polyimide filimu, pakachitsulo mtanda ndi zipangizo zina; Diisooctyl isophthalate, pulasitiki yamadzi yamafuta yopanda utoto yogwirizana bwino ndi PVC, nitrocellulose, polystyrene ndi utomoni wina, idakonzedwa.
