5-Bromovaleric acid, identified by its CAS number 2067-33-6, is a significant organic chemical compound that bridges basic research and industrial applications. As an organic acid derivative, it possesses a unique chemical structure that makes it a valuable intermediate in various synthetic pathways. Understanding its fundamental properties and applications is crucial for chemists, researchers, and procurement specialists looking to leverage its potential.

Chemically, 5-Bromovaleric acid is an aliphatic monocarboxylic acid featuring a bromine atom at the fifth carbon position. Its molecular formula is C₅H₉BrO₂, and its molar mass is approximately 181.03 g/mol. Typically, it appears as a white to off-white crystalline powder, with a melting point generally falling between 38-40°C. This physical state and melting point are important indicators for quality control and handling. While it is largely insoluble in water, it demonstrates good solubility in organic solvents like ethanol, which is a common characteristic for many organic intermediates used in synthesis.

The reactivity of 5-Bromovaleric acid stems from its bifunctional nature. The carboxylic acid group (-COOH) allows for reactions such as esterification, amidation, and salt formation. Concurrently, the bromine atom (-Br) is a good leaving group, making the molecule susceptible to nucleophilic substitution reactions. This duality enables it to act as a versatile building block in complex multi-step syntheses. For instance, it can be used to introduce a five-carbon chain with terminal functionality, which is particularly useful in creating specific molecular architectures in areas like pharmaceutical development.

The applications of 5-Bromovaleric acid are diverse and impactful. It serves as a crucial intermediate in the synthesis of pharmaceuticals, contributing to the creation of active pharmaceutical ingredients (APIs). Beyond healthcare, its utility extends to the textile industry, where it can modify fibers or dyes. In the dye industry itself, it might be used in synthesizing specific chromophores or functional dyes. The plastics industry utilizes it for developing specialized polymers, and it also finds application in the formulation of pesticides and other agrochemicals. For those seeking to buy this chemical, understanding these applications helps in assessing its value proposition and potential ROI.

When procuring 5-Bromovaleric acid, especially in bulk, it is essential to partner with a reliable manufacturer or supplier. Companies that offer high purity grades (e.g., ≥99.0%) and provide comprehensive documentation like Certificates of Analysis (CoA) are preferred. The price for this intermediate can vary, making it important to compare offers from multiple sources, particularly from established Chinese chemical manufacturers who often provide competitive wholesale prices. Whether for laboratory research or industrial-scale production, understanding the properties and broad applicability of 5-Bromovaleric acid is key to unlocking its full potential in your specific field.
