Organic synthesis is the bedrock of innovation across numerous industries, from pharmaceuticals and agrochemicals to materials science and electronics. The availability of versatile chemical building blocks is crucial for chemists to design and create novel compounds. 4-Pentylbenzoic acid (CAS 26311-45-5) is one such valuable compound, offering unique structural features that make it a sought-after reagent in various synthetic pathways. This article delves into its properties, applications in organic synthesis, and provides practical advice for procurement professionals and researchers looking to buy this chemical.

Understanding the Chemical Profile of 4-Pentylbenzoic Acid

4-Pentylbenzoic acid, identified by CAS number 26311-45-5, is an aromatic carboxylic acid. Its structure consists of a benzoic acid core with a five-carbon alkyl chain (pentyl group) attached at the para position. This combination imparts distinct chemical properties: the carboxylic acid group (-COOH) provides reactivity characteristic of acids, allowing for esterification, amide formation, and salt generation. Meanwhile, the hydrophobic pentyl chain influences solubility and intermolecular interactions, making it useful in applications where tailored physical properties are desired.

Key specifications often include:

  • Molecular Formula: C12H16O2
  • Molecular Weight: Approximately 192.26 g/mol
  • Appearance: Typically a white crystalline solid.
  • Purity: High purity, often specified as 99.5% or greater, is critical for precise synthetic transformations.
  • Melting Point: Generally in the range of 86-90°C, though specific batches may vary slightly.

These properties make it an attractive starting material or intermediate for chemists developing complex organic molecules.

Applications in Organic Synthesis

The versatility of 4-Pentylbenzoic acid stems from its dual functionality: the aromatic ring, the carboxylic acid group, and the alkyl chain. Its primary application is as a precursor for liquid crystal materials, where the pentyl chain contributes to the mesogenic properties. Beyond this, it serves as:

  • Aromatic Functionalization: The carboxylic acid can be transformed into esters, amides, acid halides, and anhydrides, which are common intermediates in synthesizing pharmaceuticals and agrochemicals.
  • Chain Extension: The pentyl group can be further modified or serve as a lipophilic tail in designing surfactants or specialty polymers.
  • Building Block for Complex Molecules: Researchers may utilize it in multi-step syntheses where its specific aromatic substitution pattern is required.

For professionals seeking to buy 4-Pentylbenzoic acid, understanding these synthetic utilities helps in identifying its value for their specific research or production goals. The availability of this compound from reliable manufacturers is key to enabling efficient organic synthesis projects.
