Cas no 21900-42-5 (2,4-dimethylbenzoyl chloride)

2,4-Dimethylbenzoyl chloride is an organic compound primarily used as an acylating agent in chemical synthesis. Its key advantages include high reactivity due to the presence of the acyl chloride functional group, enabling efficient introduction of the 2,4-dimethylbenzoyl moiety into target molecules. The compound is particularly valuable in pharmaceutical and agrochemical applications, where it serves as an intermediate in the synthesis of active ingredients. Its stability under controlled conditions and compatibility with a range of solvents further enhance its utility in laboratory and industrial settings. Proper handling is essential due to its moisture sensitivity and potential corrosivity.
