diazomethane

diazomethane的音标为/"daɪəzəʊmiːθɪə/，基本翻译为“二甲亚甲基”，速记技巧为“diazomethane [daɪəzoʊməθiːə] 二甲基甲酰胺”。

Diazomethane这个词来源于希腊语“dia”和“methane”，意思是通过或通过甲烷。它的化学式为CH3N，是一种有机化合物，可以作为合成其他化合物的中间体。

变化形式：在化学中，diazomethane可以简写为DM，它的结构式可以变化。

相关单词：

1. Dimethylformamide：是一种有机化合物，化学式为DMF，是酰胺的一种。

2. Dimethylamine：化学式为CH3NH2，是一种有机胺，是甲胺的水合物。

3. Dimethylglyoxime：是一种有机化合物，化学式为C2H4N2O，是氨基甲酸乙酯的一种。

这些单词在化学、生物学、工程学等领域都有广泛的应用，它们在英语中的使用也反映了英语作为国际通用语言的广泛性和包容性。以上回答仅供参考。
