International Chemical Safety Cards DI-n-PENTYLAMINE ICSC: 0537 Dipentylamine N-pentyl-1-pentanamine Diamylamine C10H23N / CH3(CH2)4NH(CH2)4CH3 Molecular mass: 157.3 ICSC #    0537 CAS #     2050-92-2 RTECS # RZ9100000 UN #        2841 March 25, 1999 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 51°C explosive vapour/air mixtures may be formed. Above 51°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS!  •INHALATION Burning sensation. Cough. Headache. Nausea. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.  •SKIN Redness. Serious skin burns. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Redness. Blurred vision. Severe deep burns. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Shock or collapse. (Further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: Chemical protection suit including self-contained breathing apparatus.) Fireproof. Separated from food and feedstuffs. See Chemical Dangers. Cool. Dry. Well closed. Keep in a well-ventilated room. Do not transport with food and feedstuffs.

International Chemical Safety Cards DI-n-PENTYLAMINE ICSC: 0537 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO LIGHT-YELLOW LIQUID ,WITH PUNGENT ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive gases including nitrogen oxides. Reacts violently with oxidants, acids, acid chlorides, acid anhydrides and mercury. Attacks plastics, copper, copper alloys, aluminium, zinc, zinc alloys and galvanized surfaces; water solution may attack glass. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour or its aerosol, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates severely the respiratory tract and is corrosive to the skin and to the eyes. Inhalation of vapour/mist may cause lung oedema (see Notes). The substance may cause effects on the central nervous system. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 202-203°C Melting point: -44°C Relative density (water = 1): 0.8 Solubility in water, g/100 ml: none Vapour pressure, Pa at 20°C: 40 Relative vapour density (air = 1): 5.4 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 51°C c.c. ENVIRONMENTAL DATA N O T E S Other melting points: -8°C; -32°C. Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 55°C. Environmental effects from the substance have not been investigated adequately. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
