Crystal Violet Lactone (CVL), bearing the CAS number 1552-42-7, is a critical specialty chemical widely utilized in the imaging industry, particularly in the formulation of carbonless copy paper. Its distinctive property as a leuco dye—meaning it can change color upon stimulation—makes it indispensable for applications requiring color transfer through pressure or heat.

The primary function of Crystal Violet Lactone is as a color former in carbonless copy systems. In these systems, CVL is encapsulated within microcapsules and applied to the back of the top sheet of paper. When pressure is applied, such as through writing, these microcapsules rupture, releasing the CVL. This leuco dye then reacts with a developing agent on the subsequent sheet, undergoing a chemical transformation that results in the development of a vivid blue-violet color. This efficient and clean transfer of color is the hallmark of carbonless paper technology.

For professionals in the procurement and R&D sectors, understanding the specifications of CVL is crucial. The compound, typically appearing as a white powder, boasts a molecular formula of C26H29N3O2. Manufacturers often specify a purity of 96% or higher to ensure optimal color intensity and fast color development. Furthermore, its good oil solubility is key for successful microencapsulation, a vital step in its application. When you are looking to buy Crystal Violet Lactone, it is imperative to select suppliers who can guarantee these quality standards.

Sourcing this specialized chemical effectively often involves exploring the global market. Manufacturers in China have become significant suppliers of high-quality organic intermediates, including CVL. Companies like NINGBO INNO PHARMCHEM CO.,LTD. focus on producing and distributing this leuco dye, offering competitive pricing and reliable supply chains. It is advisable for buyers to request detailed product specifications, safety data sheets (SDS), and certificates of analysis (CoA) to verify the quality and suitability of the CVL for their intended manufacturing processes. Obtaining quotes from multiple suppliers can also help in securing the best value.

In conclusion, Crystal Violet Lactone (CAS 1552-42-7) is a foundational element in many imaging solutions. By prioritizing high-purity products and partnering with reputable manufacturers and suppliers, businesses can ensure the consistent performance and quality of their end products, meeting the demands of a dynamic market.
