29081000 | [Safety Profile]
Poison by inhalation
and intraperitoneal routes. Moderately toxic
by ingestion, skin contact, and subcutaneous
routes. A severe skin and eye irritant.
Human systemic effects by inhalation:
excitement, irritability. Mutation data
reported. Combustible when exposed to
heat or flame. To fight fire, use water, spray,
mist, fog, foam, dry chemical. When heated
to decomposition it emits toxic fumes of
Cl-. See also CHLOROPHENOLS and
CHLORIDES. | [Hazardous Substances Data]

| Hazard Information | Back Directory | [General Description]
White crystals with a strong phenol odor Slightly soluble to soluble in water, depending on the isomer, and denser than water. Noncombustible. Used as an intermediate in organic synthesis of dyes and drugs. | [Reactivity Profile]
CHLOROPHENOLS, SOLID are incompatible with acid chlorides, acid anhydrides and oxidizing agents. Also incompatible with iron . Liquefy and darken in color at temperatures above 108°F. | [Air & Water Reactions]
Slightly soluble to soluble in water. | [Hazard]
Toxic by skin absorption, inhalation, or
ingestion; strong irritant to tissue. | [Health Hazard]
Inhalation causes headache, dizziness, weak pulse. Ingestion causes irritation of mouth and stomach; headache, dizziness, weak pulse. Contact with eyes causes severe irritation and burning. Contact with skin causes irritation and burn; if absorbed, causes same symptoms as inhalation. | [Potential Exposure]
Monochlorophenols are used in the
manufacture of fungicides, slimicides, bactericides, pesticides, herbicides, disinfectants, wood and glue preservatives; in the production of phenolic resins; in the extraction
of certain minerals from coal; as a denaturant for ethanol;
as an antiseptic; as a disinfectant, and others. | [Fire Hazard]
Special Hazards of Combustion Products: Toxic and irritating hydrogen chloride and chlorine gases may form in fires. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts
the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from
exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has
stopped and CPR if heart action has stopped. Transfer
promptly to a medical facility. When this chemical has
been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. | [Shipping]
