2-Chloroacetamidine monohydrochloride - Introduction
Chloroacetamidine hydrochloride is an organic compound with the chemical formula C2H4ClN · HCl, which is a white crystalline solid. The following is a description of its nature, use, formulation and safety information:
Nature:
-Chloroacetamidine hydrochloride is a solid that is readily soluble in water. When dissolved in water, a dehydration reaction occurs to produce the free form of chloroacetamidine.
-Its melting point is about 138-142°C, and its boiling point is about 203°C.
-Chloroacetamidine hydrochloric acid is an acidic solution, and its acidity mainly comes from the ions of hydrochloric acid.
Use:
-Chloroacetamidine hydrochloride can be used as a reagent in organic synthesis, and is commonly used as a catalyst for acylation reactions and acylation reactions.
-It can also be used to prepare other compounds, such as amino ketones, amides, etc.
Preparation Method:
The preparation method of chloroacetamidine hydrochloric acid is generally to react chloroacetic acid with dry ammonia, and then add hydrochloric acid for neutralization reaction. Specific preparation methods can be the following:
1. Dissolve chloroacetic acid in dry ether, and then add ammonia gas to obtain chloroacetamidine. The obtained chloroacetamidine was further added to hydrochloric acid to obtain chloroacetamidine hydrochloride.
2. add chloroacetic acid to dry methanol, and then add ammonia gas to react to generate chloroacetamidine. Finally, chloroacetamidine is added to hydrochloric acid to obtain chloroacetamidine hydrochloride.
Safety Information:
-Chloroacetamidine hydrochloride is irritating and may cause irritation to the eyes, skin and respiratory tract. Therefore, wear protective glasses and gloves during use and ensure adequate ventilation.
-Avoid contact with organics, combustibles or oxidants during storage and handling to prevent fire or explosion.
