In the intricate landscape of chemical synthesis, certain molecules serve as indispensable linchpins, enabling the creation of a vast array of valuable products. 4-Hydroxybutyl Acrylate (4-HBA), identified by CAS number 2478-10-6, is one such crucial intermediate. Its unique bifunctional nature, possessing both an acrylate ester and a primary alcohol group, renders it exceptionally versatile for a wide range of chemical transformations. For research scientists and production chemists, understanding the synthesis pathways and downstream applications of 4-HBA is fundamental to innovation in fine chemicals and pharmaceuticals. When considering the purchase of such intermediates, the reliability of the manufacturer and the clarity of product specifications are paramount.

The synthesis of 4-Hydroxybutyl Acrylate typically involves the esterification of acrylic acid or its derivatives with 1,4-butanediol. This process, when carefully controlled, yields a monomer with high purity, crucial for its demanding applications. The dual functionality of 4-HBA allows chemists to engage it in two distinct types of reactions: addition polymerization via its acrylate group, and derivatization or further reactions at its hydroxyl group. This dual reactivity is what makes it such a sought-after building block.

One of the most significant applications of 4-HBA is its role as a pharmaceutical intermediate. The hydroxyl group can be further functionalized to introduce various chemical moieties, while the acrylate group can be utilized in polymerization or as a reactive handle for conjugation. This versatility is instrumental in the synthesis of complex drug molecules where precise structural modifications are required. For pharmaceutical manufacturers, sourcing 4-HBA from reputable suppliers ensures the integrity of their synthesis pathways and the quality of their Active Pharmaceutical Ingredients (APIs).

Beyond pharmaceuticals, 4-HBA finds extensive use in the production of specialty polymers and functional materials. As a monomer, it can be polymerized to form poly(4-hydroxybutyl acrylate), which can then undergo further modifications. More commonly, it is copolymerized with other monomers to impart specific properties to the resulting polymer. Its incorporation into UV-curable coatings, inks, and adhesives enhances properties such as flexibility, adhesion, and resistance to environmental factors like acid rain and UV degradation. For companies looking to buy these advanced materials, understanding the role of 4-HBA is essential.

The demand for high-quality 4-Hydroxybutyl Acrylate as a chemical intermediate is robust. For procurement managers and R&D scientists, partnering with a manufacturer that can guarantee consistent quality, purity, and supply is critical. When seeking to purchase this versatile compound, looking for manufacturers that provide detailed technical data sheets, NMR spectra, and other analytical information can help ensure you are acquiring a product suitable for your specific synthesis needs. The price of 4-hydroxybutyl acrylate is a factor, but the assurance of quality from a dependable supplier is often a greater determinant of success in complex chemical synthesis.

In summary, 4-Hydroxybutyl Acrylate is a cornerstone intermediate in modern chemical synthesis. Its facile synthesis and versatile reactivity make it indispensable for pharmaceutical development, advanced materials, and a host of other fine chemical applications. For any organization involved in these sectors, securing a reliable supply of high-purity 4-HBA from a reputable manufacturer is a strategic imperative for driving innovation and ensuring product excellence.
