| Use | Overview 2-nitrophenyl isothiocyanates are isothiocyanates, isothiocyanates are commonly used in the construction of heterocyclic frameworks, is a class of organic synthesis intermediates and pharmaceutical intermediates with a wide range of uses, widely used in medicine, pesticides, therefore, the synthesis of isothiocyanates has been an important topic in organic chemistry. The preparation method of isothiocyanate mainly includes the following ways: Synthesis of thiophosgene: isothiocyanate is produced by direct reaction of thiophosgene and amine compound. However, the reaction requires the use of thiophosgene, which is a highly toxic volatile liquid, and its production, transportation and use are not safe, and the harm to the environment is also great. |

O-NITROPHENYL ISOCYANATE - Reference Information
| overview | 2-nitrophenyl isothiocyanate is isothiocyanate compounds, isothiocyanate is commonly used to construct heterocyclic skeletons. It is a kind of extremely versatile organic synthesis intermediates and pharmaceutical intermediates. It is widely used in the preparation of medicines, pesticides, and dyes. Therefore, the synthesis of isothiocyanates has always been an important topic in organic chemistry. The preparation methods of isothiocyanate mainly include the following ways: thio phosgene synthesis method: the direct reaction of thio phosgene and amine compounds to generate isothiocyanate. However, this reaction requires the use of thiophosphosgene, which is a highly toxic volatile liquid. Its production, transportation and use are not safe, and it is harmful to the environment. |
