Understanding the fundamental properties of chemical compounds is the bedrock of successful application and innovation. Dicyclohexyl-3,4,3',4'-tetracarboxylic dianhydride (HBPDA), CAS 122640-83-9, is a compound whose specific characteristics make it invaluable in niche scientific and industrial sectors. NINGBO INNO PHARMCHEM CO.,LTD provides insights into the key attributes of this vital intermediate.

HBPDA is characterized by its molecular formula C16H18O6 and a molecular weight of approximately 306.31 g/mol. A key physical property is its melting point, which is reliably reported at 208 °C. This consistent melting point is indicative of the compound's purity and structural integrity, crucial factors for its use in sensitive chemical reactions and polymerizations.

Chemically, HBPDA is an alicyclic dianhydride. The presence of two anhydride functional groups makes it highly reactive towards nucleophiles, particularly amines, leading to the formation of polyamic acids, which are precursors to polyimides. As mentioned in its applications, its reaction with nitriles to form oxazolines is another significant chemical pathway it enables.

The synthesis of HBPDA itself involves specific chemical processes designed to yield a high-purity product, often with a reported purity of 99% or higher. While the detailed proprietary synthesis routes are complex, the focus is on producing a compound that meets stringent quality standards. This includes ensuring minimal impurities that could interfere with subsequent reactions or polymer properties.

When considering HBPDA for your research or industrial needs, it's important to note its storage conditions, typically requiring an inert atmosphere and room temperature to maintain its stability. Proper handling and storage are essential to preserve its reactivity and purity, ensuring optimal performance in applications ranging from advanced materials to pharmaceutical intermediates.

NINGBO INNO PHARMCHEM CO.,LTD is dedicated to offering detailed technical information and high-quality HBPDA to researchers and manufacturers. Understanding these scientific fundamentals allows for the effective utilization of this compound in driving forward innovations in polymer science, organic chemistry, and beyond.
