Isophthalaldehyde, bearing the CAS number 626-19-7, is a pivotal organic compound widely utilized across various industrial and research sectors, primarily as a chemical intermediate. Its distinct chemical structure and reactivity make it an essential component in sophisticated synthesis processes. For professionals involved in chemical procurement and research, understanding the properties of Isophthalaldehyde and effective sourcing strategies is crucial for operational success.

Chemical Characteristics of Isophthalaldehyde

Isophthalaldehyde, scientifically named benzene-1,3-dicarbaldehyde, is an aromatic dialdehyde with a molecular formula of C8H6O2 and a molecular weight of 134.13 g/mol. It typically appears as a white to pale yellow crystalline powder, with a melting point generally falling between 87-88°C. This solid form is stable under recommended storage conditions, which include keeping the compound below 30°C in tightly sealed containers due to its sensitivity to air.

Regarding its solubility, Isophthalaldehyde exhibits slight solubility in water but is more soluble in common organic solvents like chloroform and ethyl acetate. This property dictates its use in various reaction media. While generally stable, it is noted to be incompatible with strong oxidizing agents, a standard precaution for aldehydes in chemical handling.

Applications Driving the Market for Isophthalaldehyde

The versatility of Isophthalaldehyde fuels its demand across multiple industries. Its primary applications include:

  • Organic Synthesis: It acts as a fundamental building block, participating in reactions like Knoevenagel condensations to form new carbon-carbon bonds, essential for creating complex organic molecules.
  • Pharmaceutical Intermediates: In the pharmaceutical sector, it is used to synthesize various APIs and complex drug molecules, where its structure can be extensively modified.
  • Material Science: It finds use in the development of specialized polymers, resins, and other advanced materials due to its ability to impart specific properties.

For those looking to buy Isophthalaldehyde, understanding these applications helps in specifying the required purity and quantity.

Procurement Strategies: Sourcing from Chinese Manufacturers

China is a leading global supplier of fine chemicals, including Isophthalaldehyde. Sourcing from Chinese manufacturers can provide significant cost advantages and ensure a steady supply, crucial for large-scale production. When selecting an Isophthalaldehyde manufacturer in China, buyers should prioritize:
