Chemical Identifiers
)
UN/NA Number - The United Nations-North America number (also called UN number or DOT number). 4-digit number identifying an individual chemical or group of chemicals with similar characteristics. Required on shipping papers; often shown on placards or labels. This numbering system was developed by the U.S. Department of Transportation, and then became the UN standard system for classifying hazardous materials.
CAS Number - Chemical Abstracts Service registry number. Unique identification number assigned to this chemical by the American Chemical Society.
CHRIS Code - 3-letter code used by the U.S. Coast Guard to identify individual chemicals included in its CHRIS (Chemical Hazards Response Information System) manual.
DOT Hazard Label - U.S. Department of Transportation hazard warning label for the chemical (such as flammable liquid or corrosive). This label must be displayed on shipped packages, railroad tank cars, and tank trucks according to specifications described in 49 CFR 172.
NFPA 704 - Text description of the diamond-shaped placard, which contains codes indicating the level of the chemical's health, flammability, and reactivity hazards, along with special hazards such as water- and air-reactivity. (The NFPA 704 diamond is also shown at the top of the datasheet.) See a guide to the NFPA diamond.

General Description
XANTHATES are salts or esters of xanthic acid ( C2H5OC(=S)SH), but the term also applies to salts or esters of any acid of the structure ROC(=S)SH. where R is an alkyl or similar radical. Xanthates are generally yellowish solids with pungent odors. Generally soluble in water.
Hazards
)
Reactivity Alerts - Special alerts if the chemical is especially reactive
(see list of reactivity alerts).
Air & Water Reactions - Special alerts if the chemical reacts with air, water, or moisture.
Fire Hazard - Description of the chemical's fire hazards (such as flammability, explosion risk, or byproducts that may evolve if the chemical is burned).
Health Hazard - Description of the chemical's health hazards (such as toxicity, flammability, or corrosivity).
Reactivity Profile - Description of the chemical's potential reactivity with other chemicals, air, and water. Also includes any other intrinsic reactive hazards (such as polymerizable or peroxidizable).
Reactive Groups - List of reactive groups that the chemical is assigned to, based on its known chemistry. Reactive groups are categories of chemicals that react in similar ways because their chemical structures are similar. Reactive groups are used to predict reactivity when you add a chemical to MyChemicals. Read more about reactive groups.

Reactivity Alerts
- Water-Reactive
Air & Water Reactions
May form carbon disulfide upon contact with moisture.
Fire Hazard
Flammable/combustible material. May ignite on contact with moist air or moisture. May burn rapidly with flare-burning effect. Some react vigorously or explosively on contact with water. Some may decompose explosively when heated or involved in a fire. May re-ignite after fire is extinguished. Runoff may create fire or explosion hazard. Containers may explode when heated. (ERG, 2008)
Health Hazard
Fire will produce irritating, corrosive and/or toxic gases. Inhalation of decomposition products may cause severe injury or death. Contact with substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution. (ERG, 2008)
Reactivity Profile
XANTHATES are O-esters of dithiocarbonic acid or xanthic acid with structure ROC(=S)SH. Xanthates are incompatible with HEAT and MOISTURE. They decompose to explosive and flammable vapors of carbon disulfide when heated or come in contact with water.

Firefighting
Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Use "alcohol" foam, dry chemical or carbon dioxide. Apply water from as far a distance as possible. Keep run-off water out of sewers and water sources. (AAR, 2003)
Non-Fire Response
Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Keep material dry. Do not apply water to point of leak in tank car or container. (AAR, 2003)
Protective Clothing
Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. Avoid breathing fumes from burning material. Avoid bodily contact with the material. Wear appropriate chemical protective gloves, boots and goggles. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. (AAR, 2003)
First Aid
Move victim to fresh air; call emergency medical care. In case of contact with material, immediately flush skin or eyes with running water for at least 15 minutes. Remove and isolate contaminated clothing and shoes at the site. (AAR, 2003)
