In the vast landscape of chemical compounds, certain molecules serve as crucial building blocks for a multitude of sophisticated applications. 7-Anilino-3-diethylamino-6-methyl fluoran, identified by its CAS number 29512-49-0 and commonly known as ODB-1, is one such versatile chemical intermediate. Its unique properties make it indispensable in industries ranging from paper manufacturing to specialty inks. This article explores its nature, utility, and where to source it.

What is a Chemical Intermediate?
A chemical intermediate is a substance that is produced during a multi-step synthesis process but is not the final desired product. Instead, it acts as a precursor, undergoing further reactions to yield the final compound. ODB-1, with its complex fluoran structure, fits perfectly into this definition, serving as a key component in the synthesis of specialized colorants.

Properties and Applications of ODB-1
ODB-1 is renowned for its thermochromic and photochromic properties, meaning it can change color when subjected to heat or light, respectively. This characteristic is fundamental to its primary applications:
  • Thermal Paper: It is a critical color former in thermal paper, reacting with a developer when heated to create images, text, and bar codes on receipts, labels, and tickets. The high purity of 7-Anilino-3-diethylamino-6-methyl fluoran ensures sharp and durable prints.
  • Carbonless Copy Paper: In this application, ODB-1 is encapsulated within microcapsules. When pressure is applied, these capsules rupture, releasing the dye to react with a developer on the sheet below, producing copies without the need for carbon paper.
  • Specialty Inks: It can also be incorporated into specialty inks for novelty items, security features, or other applications requiring color-changing effects.
The molecular formula of ODB-1 is C31H28N2O3, and its molecular weight is 476.57. Its ability to achieve a minimum purity of 99.5% is a testament to advanced synthesis and purification processes.

Sourcing High-Quality ODB-1 from China
For manufacturers requiring this essential chemical intermediate, sourcing from reliable China suppliers is often the most efficient and cost-effective option. NINGBO INNO PHARMCHEM CO.,LTD. is a prominent manufacturer that provides high-purity ODB-1. By choosing to buy ODB-1 from such a reputable China supplier, businesses can ensure they obtain a product that adheres to strict quality standards, which is vital for the consistent performance of their final products. The availability of CAS 29512-49-0 thermal paper dye in bulk quantities from these manufacturers further streamlines the procurement process.

Conclusion
7-Anilino-3-diethylamino-6-methyl fluoran (CAS 29512-49-0) is more than just a chemical; it's an enabler of advanced imaging technologies. Its role as a high-performance chemical intermediate underscores the importance of precision in chemical manufacturing and the value of reliable supply chains.
