For professionals in the chemical and pharmaceutical industries, the consistent availability of high-quality raw materials is non-negotiable. 4-Vinylbenzaldehyde, identified by CAS number 1791-26-0, is a critical organic intermediate that serves as a foundational component in numerous synthetic processes. This article aims to guide buyers on the essential aspects of procuring this compound, with a specific focus on purity requirements, diverse applications, and the advantages of sourcing from Chinese manufacturers.

4-Vinylbenzaldehyde, often referred to by its synonyms such as 4-Formylstyrene or p-Vinylbenzaldehyde, is characterized by its white powder appearance and a molecular formula of C9H8O. Its significance stems from its dual reactivity – the aldehyde group and the vinyl moiety – which enables its use in a broad spectrum of chemical reactions. For instance, in pharmaceutical research and development, it is employed as a key building block for synthesizing complex APIs and drug intermediates. The stringent purity requirements in this sector, often demanding ≥99%, underscore the importance of selecting suppliers with robust quality control measures.

Beyond its role in pharmaceuticals, 4-Vinylbenzaldehyde is integral to the agrochemical industry, acting as a precursor for herbicides and pesticides. Its contribution to creating more effective crop protection solutions highlights its value to formulators and manufacturers. Furthermore, in material science, it functions as a specialty monomer, allowing for the development of polymers with unique functionalities and performance characteristics.

When embarking on the purchase of 4-Vinylbenzaldehyde, buyers are advised to consider several critical factors. Firstly, the purity level must align with the intended application. For research and analytical purposes, higher purity might be essential, while for certain industrial syntheses, slightly lower, more cost-effective grades might suffice. Secondly, understanding the supplier's capacity for consistent production and reliable delivery is paramount, especially for bulk orders. Many companies in China have emerged as leading manufacturers and suppliers, offering competitive pricing and a strong commitment to international quality standards.

To ensure a successful procurement, it is recommended to request detailed product specifications, including a Certificate of Analysis (CoA), which typically outlines purity, moisture content, and other critical parameters. Engaging with suppliers who can provide samples for preliminary testing is also a prudent step. By carefully evaluating manufacturers and their offerings, businesses can secure a dependable source of 4-Vinylbenzaldehyde, thereby supporting their research, development, and production goals.

In conclusion, 4-Vinylbenzaldehyde (CAS 1791-26-0) is a versatile and valuable intermediate. For procurement managers and research scientists, a focused approach to sourcing, emphasizing product purity, application suitability, and supplier reliability, is key to successful acquisition and utilization.
