Ethyl 4-Bromobutyrate (CAS 2969-81-5) is a fundamental chemical intermediate that underpins numerous synthetic pathways in pharmaceuticals, agrochemicals, and fine chemical industries. As a manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. possesses a deep understanding of its synthesis, properties, and the critical role it plays for our customers. This article provides a manufacturer's perspective on how this versatile compound is produced and why its specific characteristics are so vital for various applications. For those looking to buy this intermediate, understanding its genesis and attributes from a reliable supplier is key.

The synthesis of Ethyl 4-Bromobutyrate typically involves the esterification of 4-bromobutyric acid with ethanol, or alternatively, the reaction of gamma-butyrolactone with hydrogen bromide followed by esterification with ethanol. Various methods exist, often optimized for yield, purity, and cost-effectiveness. For instance, one common route involves reacting 4-bromobutyric acid with ethanol in the presence of an acid catalyst. Another pathway might utilize ?-butyrolactone reacting with hydrogen bromide to form 4-bromobutyric acid, which is then esterified. Our manufacturing processes are refined to ensure high yield and purity, typically achieving a product appearance of colorless to yellow clear liquid with a purity of ≥98.0%.

The key properties of Ethyl 4-Bromobutyrate that make it so valuable include its bifunctional nature. The ester group offers a site for further derivatization or can be hydrolyzed. More critically, the primary alkyl bromide is a reactive electrophile, readily participating in SN2 reactions with a wide range of nucleophiles. This allows chemists to easily introduce the 4-ethoxycarbonylbutyl chain into target molecules. Its molecular weight is approximately 195.05 g/mol, and it has a boiling point in the range of 80-82°C at reduced pressure (e.g., 10 mm Hg). These physical and chemical properties are essential for chemists when planning synthesis strategies and often prompt searches like 'ethyl 4-bromobutyrate specifications' or 'what is ethyl 4-bromobutyrate used for.'.
