2-Iodo-4-nitroaniline CAS 6293-83-0

What 2-Iodo-4-nitroaniline Is

2-Iodo-4-nitroaniline is a tri-substituted aniline, with an amino group, a nitro group para to it and an iodine atom ortho to it, supplied as yellow to dark yellow crystals. In dye production the amino group is diazotized and coupled to build disperse and other azo dyes, where the nitro and iodine groups carry the shade toward deep, fast colors. In fine chemical and pharmaceutical synthesis the iodine acts as the reactive handle in coupling and substitution steps that build more complex molecules. The material is light and air sensitive, so it is produced and packed to keep color and assay stable, with standard industrial material around 98% by GC.

Disperse Dyes and Other End Uses

• Disperse and azo dyes. Used as a diazo component that is diazotized and coupled to form deep-shade disperse dyes for polyester and other synthetic fibers, where the halogen and nitro substitution support shade and fastness.
• Pharmaceutical fine chemicals. A halogenated building block whose iodine is replaced or coupled to produce active ingredient intermediates and heterocyclic compounds.
• Custom organic synthesis. Serves as a ready-made nitro and iodo functionalized aniline for research, contract synthesis and specialty chemical development.

Typical Specifications

The table shows a standard industrial lot as a reference; higher assay or reagent-grade material and other particle forms are available on request.

Packaging, Documents and Ordering

• Packed light-proof and sealed in 25 kg fiber drums or 200 kg FIBC bags with liner; store in a cool, dry, ventilated, dark place, away from heat, light and oxidizers, and limit air exposure after opening.
• Classified as an irritant (GHS07), the dust can irritate skin, eyes and respiratory tract, so gloves, goggles and a dust mask are used when handling, and labels follow the SDS for each order.
• Every lot ships with a COA showing GC assay, melting point, moisture and color, together with SDS, and small samples and trial orders are supported for this fine intermediate. For a quote, send the CAS, target purity, quantity, packing preference and destination port.
