Ethyl bromide

Bromoethane_74-96-4_High Purity Pharmaceutical & Pesticide Intermediate_Ethylating Agent

Core Product Parameters:

Bromoethane, also known as ethyl bromide, with CAS registry number 74-96-4, molecular formula C₂H₅Br, and molecular weight 108.97, is a volatile colorless liquid and an important short-chain aliphatic bromoalkane. Due to its low molecular weight and high reactivity, bromoethane is widely used as an efficient ethylating agent, capable of introducing ethyl groups into organic molecules under mild conditions. It serves as a key raw material in the synthesis of various fine chemicals.

Specifications & Quality Control:

We supply high-purity bromoethane products, with standard specifications ≥99.0% and pharmaceutical grade ≥99.5%. Strict rectification control ensures low moisture, low acid value, and low non-volatile impurity content. The product is monitored by GC chromatography to guarantee batch-to-batch consistency, meeting the needs of various scenarios from laboratory R&D to industrial production.

Main Application Fields:

Bromoethane is a versatile and important chemical intermediate. Its primary applications include:

Pharmaceutical and Pesticide Synthesis: Used in the synthesis of various pharmaceutical intermediates (e.g., sedatives, antibiotics) and pesticide active ingredients to achieve ethylation modification.

Fine Chemicals and Materials: Serves as an ethylating agent in the production of dyes, fragrances, surfactants, and liquid crystal material intermediates.

Organic Synthesis and Research Reagents: Commonly used as a reagent in Grignard reactions and alkylation reactions, widely applied in universities, research institutes, and corporate R&D centers.
