Chelora Chemicals UAE supplies Ortho Phenylene Diamine (o-Phenylenediamine, CAS 95-54-5) to agrochemical and pharmaceutical manufacturers, dye and pigment producers, polymer makers and fine-chemical companies across Dubai, Abu Dhabi, Sharjah and all seven Emirates, with batch-wise COA, sealed packing and fast GCC delivery.
Ortho Phenylene Diamine (o-Phenylenediamine, 1,2-Diaminobenzene, OPD) is an aromatic diamine supplied as a colourless to tan or brown crystalline solid. Its two adjacent amino groups make it the classic building block for benzimidazole and quinoxaline ring systems.
It is the key raw material for benzimidazole fungicides such as Carbendazim, Benomyl and Thiabendazole, and is also used in pharmaceutical intermediates, dyes and pigments, corrosion inhibitors and high-performance polymers.
As an established chemical supplier in the UAE, Chelora Chemicals sources Ortho Phenylene Diamine from approved manufacturers with consistent purity and controlled colour, and delivers it to customers in Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain, as well as export customers in Saudi Arabia, Oman, Qatar, Kuwait, Bahrain, Africa and South Asia.
