In the realm of fine chemicals, certain intermediates play disproportionately large roles due to their versatility and reactivity. Isophthalaldehyde (CAS 626-19-7), also known as benzene-1,3-dicarbaldehyde, is precisely one such compound. Its significance as a building block in various synthesis pathways makes it a critical material for industries ranging from pharmaceuticals to specialty polymers. For procurement professionals and chemists, understanding how to efficiently source this compound is essential.

The Chemical Profile of Isophthalaldehyde

Isophthalaldehyde is characterized by two aldehyde groups situated on a benzene ring at the 1,3-positions. This molecular architecture dictates its chemical behavior and utility. Typically supplied as a crystalline powder, its physical properties such as a melting point of 87-88°C and slight water solubility, along with better solubility in organic solvents, guide its application in various reaction media. As a sensitive compound, proper storage, often below 30°C and in well-sealed containers, is recommended to maintain its integrity.

Industrial Applications and Demand Drivers

The demand for Isophthalaldehyde is driven by its extensive use as a:

  • Fine Chemical Intermediate: It serves as a foundational component in the synthesis of a broad range of specialty chemicals, including advanced polymers, resins, and high-performance materials.
  • Pharmaceutical Building Block: In the pharmaceutical industry, Isophthalaldehyde is a key intermediate for creating complex APIs and drug discovery molecules. Its reactive aldehyde groups allow for extensive structural modification.
  • Research Chemical: For laboratories engaged in organic synthesis and materials science research, high-purity Isophthalaldehyde is indispensable for experimental development and validation.

When seeking to buy Isophthalaldehyde, it is important to specify the required purity level, as applications in sensitive areas like pharma demand very high standards.

Strategic Sourcing from China: A Buyer's Advantage

China has become a global powerhouse for fine chemical manufacturing, offering significant advantages for international buyers seeking materials like Isophthalaldehyde. By partnering with an established Isophthalaldehyde manufacturer in China, businesses can often achieve more competitive Isophthalaldehyde prices and ensure a more stable supply.
