The Uses of 3-Chloro-2-methylaniline

3-Chloro-2-Methylaniline can be used for dyeing cotton, viscose, silk, nylon and acetate, as well as printing on cotton. It is mainly used for dyeing red, such as coupling with chromophenol AS, AS-BO, AS-ITR, etc.

The Uses of 3-Chloro-2-methylaniline

Intermediate.

Preparation

By 1-Methyl-2-nitrobenzene chlorination byproducts 3-Chloro-2-methylbenzenamine?reduction.

Hazard

Toxic by ingestion or inhalation.

Safety Profile

Poison by ingestion. Mutation data reported. When heated to decomposition it emits toxic fumes of Cl and NOx. See also other chloro toluidine entries.

Potential Exposure

Most of the isomers are used in dyestuff manufacture. The 3-chloro-para isomer is used to kill birds. It is marketed as pelleted bait for control of bird populations.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.
Note to physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobinemia in urine.

storage

Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with chloromethylanilines you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, well-ventilated area. Sources of ignition, such as smoking and openflames, are prohibited where Choromethyl anilines are handled, or stored in a manner that could create a potential fireor explosion hazard. A regulated, marked area should beestablished where this chemical is handled, used, or stored incompliance with OSHA Standard 1910.1045.

Shipping

Chlorotoluidines require a label of“POISONOUS/TOXIC MATERIALS.” They fall in DOTHazard Class 6.1 and Packing Group III.

Incompatibilities

Incompatible with oxidizers, strong acids; chloroformates, and acid anhydrides, isocyanates, aldehydes forming fire and explosive hazards.
