In the precise world of microelectronics manufacturing, every component matters, and understanding the specifications of chemical inputs is paramount. For photoresist applications, where materials must meet exacting standards, detailed product knowledge is essential for procurement managers and R&D scientists. This article delves into the key specifications of Vat Blue 43 (CAS 1327-79-3), a compound that plays a role in specialized electronic formulations, and highlights why these details are critical when you are looking to buy Vat Blue 43.

Firstly, the CAS number, 1327-79-3, is the universal identifier for Vat Blue 43. This number is crucial for ensuring you are sourcing the correct chemical compound and for accurate record-keeping and regulatory compliance. When you search for this product, always verify the CAS number to avoid costly errors. As a leading supplier of electronic chemicals, we ensure that all our product listings clearly display the correct CAS number, providing transparency for our clients.

The molecular formula (C18H12N2O) and molecular weight (274.32) provide fundamental chemical information, essential for formulators calculating precise dosages and understanding reaction stoichiometry. This data is typically found on product datasheets and is a primary consideration for scientists working on new resist formulations.

Beyond these basic identifiers, physical properties are also important. Vat Blue 43 is described as having a density of 1.26 g/cm³, a boiling point of 494.643 °C at 760 mmHg, and a flash point of 252.951 °C. These properties are critical for handling, storage, and safety assessments in an industrial setting. For instance, understanding the flash point is vital for determining appropriate fire safety measures, a key concern for any procurement manager responsible for chemical inventory.

While Vat Blue 43 itself might not be a primary photoactive component in all standard photoresists, its inclusion in certain formulations or related precursor materials in the electronics industry necessitates a focus on its purity and specific performance characteristics. When you purchase Vat Blue 43, especially for applications demanding high precision, understanding the manufacturer's purity standards is vital. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier in China, emphasizes the high purity of its electronic-grade chemicals, ensuring they meet the demanding requirements of the electronics sector.

The EINECS number (215-499-2) is another regulatory identifier relevant for European markets, ensuring compliance with chemical inventory regulations. For international buyers, checking for relevant regulatory identifiers is a standard part of the due diligence process.

In summary, when considering the procurement of Vat Blue 43 for any application, particularly within the demanding field of photoresists, a thorough understanding of its specifications is non-negotiable. From CAS and EINECS numbers to detailed physical properties and purity levels, these details ensure that you are sourcing the right material from a reliable manufacturer. If you are looking to purchase electronic chemicals like Vat Blue 43, always consult detailed product specifications to ensure they align with your project's needs.
