1309595-29-6 - Introduction
N-(trimethoxysilyl propyl) ethylenediamine triacetic acid tripotassium salt, often abbreviated as TESPA. It is a chemical compound with the following properties:
1. Appearance: TESPA is a white crystalline powder.
2. Solubility: TESPA is easily soluble in water, resulting in a weak alkaline solution.
3. Stability: TESPA is stable at room temperature, but may lose its stability under the influence of acidic environment and high temperature.
TESPA has a variety of uses in the laboratory and industry, including:
1. Buffer: TESPA can be used as a buffer for biochemical experiments to help maintain the acid-base balance of the solution.
2. Complexing agent: TESPA can be used to coordinate metal ions, thus playing an important role in the synthesis of catalysts and coordination compounds.
3. Compound synthesis: TESPA can be used as an important organic reagent to participate in the synthesis of organic compounds, such as the synthesis of peptides.
The preparation method of TESPA generally includes the following steps:
1. N-methyldimethylaminoethyl triacetic acid (EDDA) is reacted with triethylamine to generate a triethylamine salt of ethylenediamine triacetate (EDTA).
2. The triethylamine salt of ethylenediamine triacetate is reacted with trimethoxychlorosilane to generate N-(trimethoxysilyl propyl) ethylenediamine triacetate.
3. Finally, the obtained product is reacted with potassium carbonate to form N-(trimethoxysilyl propyl) ethylenediamine triacetic acid tripotassium salt.
Some safety information to note when using TESPA:
1. Avoid direct contact: TESPA should avoid direct contact with skin, eyes and respiratory tract. Wear suitable safety protective equipment during operation.
2. Good ventilation: When using TESPA, a well-ventilated place should be maintained to avoid deposition and inhalation of dust.
3. Storage Note: TESPA should be stored in a dry, cool place to avoid contact with acidic substances.
In summary, N-(trimethoxysilyl propyl) ethylenediamine triacetic acid tripotassium salt has certain chemical properties and multiple uses, and it is necessary to pay attention to safe operation during use. If necessary, please use it in the laboratory or under professional guidance.
