1. 2-Nitrothiophene CAS 609-40-5 is a synthetic organic compound produced by the nitration of thiophene using a mixture of acetic anhydride and fuming nitric acid .
2. In the classic laboratory synthesis, thiophene dissolved in acetic anhydride is added to a nitric acid-acetic acid solution while maintaining the temperature below room temperature to control the reaction .
3. The resulting product is obtained as pale yellow crystals after ice treatment and filtration, with total yields of 70-85% of theoretical amount, and 2-Nitrothiophene is commercially available from chemical suppliers worldwide .
1. 2-Nitrothiophene is classified as a hazardous substance with signal word "Warning," and 2-Nitrothiophene is suspected of causing genetic defects (H341) .
2. 2-Nitrothiophene CAS 609-40-5 is harmful if swallowed, in contact with skin, or if inhaled (H302 + H312 + H332), and 2-Nitrothiophene requires wearing protective gloves, clothing, and eye protection when handling .
3. When handling 2-Nitrothiophene, avoid breathing dust, ensure adequate ventilation, and wash skin thoroughly after handling, and if exposed or concerned, seek medical advice immediately .
1. Store 2-Nitrothiophene in a cool, dry, well-ventilated place with the container tightly closed, preferably in a dark place below 15°C (59°F) .
2. Store 2-Nitrothiophene CAS 609-40-5 under inert gas to prevent degradation, as 2-Nitrothiophene is air-sensitive and light-sensitive .
3. Store 2-Nitrothiophene locked up and away from foodstuff containers, and keep 2-Nitrothiophene separate from incompatible materials .
