methoxylation（甲氧基化）是有機化學中引入甲氧基（-OCH₃）的化學反應，常見于藥物合成和有機中間體制備。以下是詳細解釋：
如需更專業的反應式或應用案例，可參考科學數據庫（如ScienceDirect）。
Methoxylation（甲氧基化）is a chemical process that adds a methoxy group to a molecule. The resulting product is called a methoxylated compound. This process is commonly used in the pharmaceutical industry, as well as in the synthesis of organic compounds.
Methoxylation is the process of adding a methoxy group (-OCH3) to a molecule. This process is used to modify the properties of a compound, such as its solubility and reactivity. Methoxylated compounds are often used in the production of drugs, as they can improve the pharmacokinetics and pharmacodynamics of a compound.
Methoxylation is a common process in the pharmaceutical industry, where it is used to modify drug molecules. The addition of a methoxy group can improve the drug's solubility, stability, and bioavailability. Methoxylated compounds are also used in the synthesis of fragrances, dyes, and other organic compounds.
There are no commonly accepted antonyms for methoxylation, as it is a specific chemical process. However, one could use the term "demethoxylation" to describe the removal of a methoxy group from a molecule.
In summary, methoxylation is a chemical process used to add a methoxy group (-OCH3) to a molecule. This process is used to modify the properties of a compound, such as its solubility and reactivity. Methoxylated compounds are commonly used in the pharmaceutical industry and in the synthesis of organic compounds.
