Danger

Chemical: Cyclohexanamine, N,N-dimethyl-

Cyclohexanamine, N,N-dimethyl- is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Cyclohexanamine, N,N-dimethyl- are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)

Status: Active Update: 28-02-2023 https://echa.europa.eu/registration-dossier/-/registered-dossier/13521

Cyclohexyldimethylamine: Does not have an individual approval but may be used under an appropriate group standard

The New Jersey Worker and Community Right to Know Act requires public and private employers to provide information about hazardous substances at their workplaces. (N.J.S.A. 34:5A-1 et. seq.)

Behavior in Fire: Dangerous when exposed to heat or flame. Can react vigorously with oxidizing materials. (USCG, 1999)

· Flammable/combustible material.

· Flammable/combustible material.

Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 42.2 °C explosive vapour/air mixtures may be formed.

Inhalation of high concentration of vapor will will produce irritation of the respiratory tract and lungs. Inhalation of large quantities of vapor may be fatal. (USCG, 1999)

· May cause toxic effects if inhaled or ingested.

· May cause toxic effects if inhaled or ingested.

A corrosive substance that can cause injury to the skin, eyes, and respiratory tract; Inhalation may cause pulmonary edema; Can be absorbed through skin; [ICSC] Irritating or corrosive to animal skin; Irritating to rabbit eyes; Not sensitizing to guinea pig skin using skin painting test; [IUCLID] Causes muscle contraction or spasticity in lethal-dose studies of mice (inhalation and oral routes); [RTECS] Causes burns; Toxic if inhaled; [Alfa Aesar MSDS]

DIMETHYLCYCLOHEXYLAMINE neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Extinguishing Agents: Carbon dioxide, dry chemical powder, polymer or alcohol foam. (USCG, 1999)

Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

· ELIMINATE all ignition sources (no smoking, flares, sparks or flames) from immediate area.

General First Aid:

General First Aid:

· Wear positive pressure self-contained breathing apparatus (SCBA).

· Wear positive pressure self-contained breathing apparatus (SCBA).

Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Collect leaking and spilled liquid in sealable containers as far as possible. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.
