The vibrant displays that define modern consumer electronics owe much of their brilliance to advanced organic materials. Central to the development and manufacturing of these materials, particularly for OLED (Organic Light-Emitting Diode) technology, is the reliable supply of key chemical intermediates. Procyanidin B3 (CAS 23567-23-9) stands out as a compound of significant importance in this domain. For researchers and manufacturers in the electronic chemicals sector, understanding its properties and sourcing it effectively is paramount.

What is Procyanidin B3?

Procyanidin B3, identified by its CAS number 23567-23-9, is a type of proanthocyanidin, a class of polyphenolic compounds. Its molecular formula is C30H26O12, and it has a molecular weight of approximately 578.523 g/mol. In the context of electronic chemicals, it is often utilized as an intermediate or a building block in the synthesis of more complex molecules required for OLED device fabrication. Its unique chemical structure lends itself to contributing specific electronic or optical properties to the final materials.

Properties and Forms for Manufacturing

The utility of Procyanidin B3 in manufacturing is often dictated by its physical properties. Manufacturers typically offer it in two forms: a powder or a liquid. This versatility allows formulators to choose the most suitable form for their specific synthesis routes or deposition techniques. The purity level is a critical specification for OLED applications, with 99% purity being a common requirement to ensure consistent performance and prevent detrimental effects on device efficiency and lifespan. Its density is noted at 1.705 g/cm3, and it has a high boiling point (955.3 °C at 760 mmHg), indicating thermal stability under certain processing conditions.

Sourcing Procyanidin B3: The Role of Chinese Manufacturers

China has become a leading global supplier of fine chemicals and electronic intermediates. When procuring Procyanidin B3 (CAS 23567-23-9), manufacturers and suppliers in China offer several advantages. These include substantial production capacities, often stated as supply abilities of around 50 Tons, enabling them to meet large-scale industrial demands. They also provide competitive pricing due to optimized manufacturing processes and supply chains. Furthermore, companies in China are accustomed to international trade, offering flexible payment options (L/C, T/T, PayPal) and diverse Incoterms (FOB, CFR, CIF, EXW), alongside robust logistics solutions via ocean, land, and air freight (including DHL and TNT).

Applications in OLED Technology

The primary application of Procyanidin B3 in the chemical industry is its role as an intermediate in the creation of organic materials for OLED displays. These materials are responsible for emitting light when an electric current passes through them. The precise chemical structure of Procyanidin B3 can be modified or incorporated into larger molecules that function as emissive layers, charge transport layers, or host materials within the OLED stack. This enables the creation of displays that are thinner, more energy-efficient, and capable of producing vibrant colors.

For companies involved in OLED material synthesis, securing a reliable supply of high-purity Procyanidin B3 from experienced manufacturers is a strategic imperative. Partnering with a dedicated supplier ensures the consistency and quality necessary for cutting-edge electronic applications.
