Chelora Chemicals UAE supplies 2-Amino-4-Nitrophenol (CAS 99-57-0) to dye and pigment manufacturers, hair-colour formulators and fine-chemical producers across Dubai, Abu Dhabi, Sharjah and all seven Emirates, with batch-wise COA, sealed packing and fast GCC delivery.
2-Amino-4-Nitrophenol is an aromatic compound with a hydroxyl, an amino and a nitro group on one benzene ring. It is supplied as an orange to dark brown crystalline powder that is slightly soluble in water and soluble in alcohol and alkaline solutions.
It is mainly a dye intermediate, used to make azo, metal-complex (chrome) and leather and wool dyes. It is also used in semi-permanent hair-colour formulations where regulations permit, in pigment synthesis and as a starting material for other fine-chemical intermediates.
As an established chemical supplier in the UAE, Chelora Chemicals sources 2-Amino-4-Nitrophenol from approved manufacturers with high assay, consistent shade and low insoluble and isomeric impurities, 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.

Hazardous. 2-Amino-4-Nitrophenol is an aromatic nitro-amine: treat it as harmful if swallowed, inhaled or absorbed through the skin, as an irritant to skin, eyes and airways and as a possible skin sensitiser. It is a combustible solid and its dust can form explosive mixtures with air. Always refer to the supplied SDS for the full classification.

Treat it as hazardous. 2-Amino-4-Nitrophenol is an aromatic nitro-amine that is harmful by swallowing, inhalation and skin contact, irritating to skin, eyes and airways and a possible skin sensitiser, and its dust is combustible. Use protective equipment and follow the SDS.
Yes. We export from the UAE to Saudi Arabia, Oman, Qatar, Kuwait, Bahrain, East and West Africa, South Asia and other markets on EXW, FOB, CFR, CIF, DAP or DDP terms, subject to the import rules of each destination.
Yes. Samples are available for qualification on request, together with the COA and SDS, so your QC or R&D team can approve the material before a commercial order.
It is used in some semi-permanent and oxidative hair-colour formulations in certain markets, but permitted use and maximum concentrations are set by each market's cosmetic regulations. Check the rules that apply to your product and destination before formulating.
Always quote the CAS number (99-57-0) and the structure in your enquiry. Several nitro-aminophenol isomers look similar and have different shades, so we confirm the isomer on the COA before dispatch.
