Index: content ≥ 99.9 moisture ≤ 0.1% Application: Pharmaceutical industry for the manufacture of vitamin A, diclopenicillin, liyanning and other drugs.

Molecular formula: C₇H₁₄ Index: content ≥ 99.5 moisture ≤ 0.05% Uses: medicine, used as a solvent, chromatographic analysis of standard substances, and as a standard calibration thermometer, also used in organic synthesis.

Molecular formula: C₃H₇NO Application field: It is not only a very wide range of chemical raw materials, used in pharmaceuticals, pesticides, chemical synthesis, but also a very wide range of excellent solvents. It can be mixed with water and most organic solvents, and has good solubility for a variety of organic compounds and inorganic compounds.

Chemical formula: C₂H₃N Index: content ≥ 99.9 moisture ≤ 0.1% Uses: Acetonitrile can be used for the synthesis of a variety of pharmaceutical and pesticide intermediates. Acetonitrile is a polar organic solvent, which has good solubility for grease, inorganic salt, organic matter and polymer compound. It can clean the grease, wax, fingerprint, corrosive agent and flux residue on the silicon wafer. Therefore, high purity acetonitrile can be used as a semiconductor cleaning agent. In addition to the above applications, acetonitrile can also be used as a raw material for organic synthesis. In addition, acetonitrile is also used in textile dyeing and coating formulations, and it is also an effective stabilizer of chlorinated solvents.
