Pivaloylacetonitrile, also known as Cyanopinacolone and 4,4-Dimethyl-3-oxovaleronitrile, is a crucial intermediate in organic synthesis with the CAS number 59997-51-2. It has a molecular formula of C7H11NO and a molar mass of 125.17 g/mol. This white to cream crystalline powder has a melting point of 66-69°C and a boiling point of 125-126°C at 22 mm Hg. It is insoluble in water and has a density of 1.0459 g/cm³. Pivaloylacetonitrile is used in the synthesis of pharmaceuticals, such as 1,1-dimethyl-3-uracil, and pesticides. It also serves as a raw material for film photosensitizers in photographic processes. For optimal stability, it should be stored in a dark, dry place at room temperature. Proper handling with personal protective equipment (PPE) is essential to avoid exposure risks. This compound's versatility makes it valuable in both pharmaceutical and agricultural industries.
Acetonitrile, also known as AN or Methyl cyanide, is a solvent integral to the chemical industry with CAS number **75-05-8**. It has a molecular formula of C2H3N, and a molar mass of **41.05 g/mol**. This colorless liquid has a density of **0.7857 g/cm³**, a melting point of **-46°C**, and a boiling point of **81-82°C**. Notable for its miscibility with water and organic solvents, Acetonitrile is used in the extraction of monomers, high-pressure liquid chromatography (HPLC), spectrophotometric determinations, and the recrystallization of steroids. It's highly flammable with a flash point of **2°C** and requires careful handling, with an oral LD50 of **3800mg/kg** in rats. Acetonitrile should be stored away from fire and heat, between **+5°C to +30°C**. Its role as a standard substance for chromatographic analysis and its solvency properties make it essential in analytical chemistry and synthesis processes.
Isobutyronitrile, also known as 2-Cyanopropane, is a chemical intermediate with the CAS number 78-82-0. It has a molecular formula of C4H7N, and a molar mass of 69.11 g/mol. This colorless liquid has a density of 0.770 g/mL at 20°C, a melting point of -72°C, and a boiling range of 107-108°C. It's insoluble in water but soluble in ethanol and ether, making it useful in various chemical reactions. Isobutyronitrile is utilized in the synthesis of the insecticide diazinon, as a raw material for isobutyamidine, in the production of acrylic resins, and for synthesizing 2-Isopropyl-4-methyl-6-hydroxy Pyrimidine. It is toxic, with an oral LD50 of 102 mg/kg in rats, and requires careful handling and storage. Its role in agriculture and industrial chemistry is significant, but safety protocols must be strictly followed due to its high toxicity.
