Regulation (EC) No 1907/2006 1 - Product and Company Information Product NameN,N-DIMETHYLTHIOACETAMIDE - 250 MG 2 - Hazards Identification SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT Harmful if swallowed.
3 - Composition/Information on Ingredients Product NameCAS #EC noAnnex I Index Number N,N-DIMETHYLTHIOACETAMIDE631-67-4 NoneNone FormulaC4H9NS Molecular Weight 103,1800 AMU 4 - First Aid Measures AFTER INHALATION If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. AFTER SKIN CONTACT In case of skin contact, flush with copious amounts of water for at least 15 minutes. Remove contaminated clothing and shoes. Call a physician. AFTER EYE CONTACT In case of contact with eyes, flush with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating the eyelids with fingers. Call a physician. AFTER INGESTION If swallowed, wash out mouth with water provided person is conscious. Call a physician. 5 - Fire Fighting Measures ALDRICHwww.molbase.com EXTINGUISHING MEDIA Suitable: Carbon dioxide, dry chemical powder, or appropriate foam. Water spray. SPECIAL RISKS Specific Hazard(s): Emits toxic fumes under fire conditions. SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. 6 - Accidental Release Measures PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL Evacuate area. PROCEDURE(S) OF PERSONAL PRECAUTION(S) Wear self-contained breathing apparatus, rubber boots, and heavy rubber gloves. METHODS FOR CLEANING UP Absorb on sand or vermiculite and place in closed containers for disposal. Ventilate area and wash spill site after material pickup is complete. 7 - Handling and Storage HANDLING Directions for Safe Handling: Avoid prolonged or repeated exposure. Do not breathe vapor. Avoid contact with eyes, skin, and clothing. STORAGE Conditions of Storage: Keep tightly closed. 8 - Exposure Controls / Personal Protection ENGINEERING CONTROLS Safety shower and eye bath. Mechanical exhaust required. GENERAL HYGIENE MEASURES Wash thoroughly after handling. PERSONAL PROTECTIVE EQUIPMENT Respiratory Protection: Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU). Where risk assessment shows air-purifying respirators are appropriate use a full-face respirator with multi-purpose combination (US) or type ABEK (EN 14387) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Hand Protection: Compatible chemical-resistant gloves. Eye Protection: Chemical safety goggles. 9 - Physical and Chemical Properties AppearancePhysical State: Liquid PropertyValueAt Temperature or Pressure ALDRICHwww.molbase.com pH N/A BP/BP RangeN/A MP/MP RangeN/A Flash PointN/A FlammabilityN/A Autoignition TempN/A Oxidizing Properties N/A Explosive Properties N/A Explosion LimitsN/A Vapor PressureN/A Partition Coefficient Log Kow: 0,398 ViscosityN/A Vapor DensityN/A Saturated Vapor Conc.
