For chemists and material scientists, a deep understanding of a chemical intermediate's properties is fundamental to its successful application. 4-(Bromomethyl)Phenylacetic Acid (CAS: 13737-36-5) is a compound that offers a unique combination of features, making it a valuable asset in various synthesis projects. This article delves into its key properties and highlights why sourcing from dependable manufacturers is crucial for its optimal utilization.

At its core, 4-(Bromomethyl)Phenylacetic Acid is an aromatic carboxylic acid. Its molecular formula is C9H9BrO2, with a molecular weight of 229.07. The compound typically presents as a White to light beige crystalline powder, indicating a solid state under standard conditions. Its melting point, usually in the range of 179-183 °C, further confirms its solid nature and provides an important parameter for quality control and material identification.

The real power of 4-(Bromomethyl)Phenylacetic Acid lies in its functional groups and their reactivity. The presence of a bromomethyl group (-CH2Br) makes it an excellent electrophile, readily participating in nucleophilic substitution reactions. This reactivity is the cornerstone of its utility as an organic synthesis intermediate. Chemists can easily attach various nucleophilic groups to the benzylic carbon, allowing for the construction of complex carbon skeletons and the introduction of diverse functionalities.

The carboxylic acid group (-COOH) provides another avenue for chemical modification. It can undergo esterification, amidation, or salt formation, further expanding the synthetic possibilities. This dual functionality—the reactive bromomethyl group and the versatile carboxylic acid—makes it a sought-after building block for intricate molecular designs. Its role as a pharmaceutical intermediate is often linked to its ability to form key linkages in drug molecules.

Stability is another critical property for any chemical intermediate. 4-(Bromomethyl)Phenylacetic Acid is generally stable under normal temperatures and pressures. This characteristic simplifies its handling, storage, and transportation, reducing logistical challenges for both suppliers and end-users. However, like many reactive organic compounds, appropriate storage conditions, often recommended to be cold and in an inert atmosphere, should be followed to maintain its integrity over time.

When seeking to buy 4-(Bromomethyl)Phenylacetic Acid, understanding these properties is key to evaluating potential suppliers. High purity (e.g., 95%min or more) is essential to ensure that the compound performs as expected in your synthesis. Reliable manufacturers will clearly define these properties and provide supporting documentation. Investing in a product with well-characterized properties from a trusted source ensures predictable results and efficient project progression, ultimately impacting the quality and cost-effectiveness of your final product.
