For professionals in the chemical industry, understanding the nuances of key intermediates is crucial for successful product development and manufacturing. Crystal Violet Lactone (CVL), identified by CAS 1552-42-7, is one such compound that plays a significant role in various imaging and coloring applications. As a leading B2B supplier, we aim to provide comprehensive information to help procurement managers, research scientists, and product formulators make informed decisions when they need to buy this vital chemical.

What is Crystal Violet Lactone?

Crystal Violet Lactone is a leuco dye, meaning it exists in a colorless state but can be converted into a colored form through a chemical reaction. Its molecular formula is C26H29N3O2, and it's characterized by its white to yellowish-brown crystalline powder appearance. With a melting point typically around 180-183°C, it is stable under ordinary storage conditions. Its primary function is as a color former, a critical component in systems that require color generation upon specific stimuli, such as pressure or heat.

Key Applications of CVL (CAS 1552-42-7)

The most prominent applications for Crystal Violet Lactone include:

  • Carbonless Copying Paper (NCR Paper): CVL is essential for creating the distinct blue images seen on multi-part forms. When the microcapsules containing CVL rupture under pressure, they release the dye, which reacts with an acidic developer to produce a visible color.
  • Thermal Paper: In the formulation of thermal coatings for receipts, labels, and tickets, CVL acts as a colorant that develops a specific hue (often blue) when heated by a thermal printer.
  • Textile and Printing Auxiliaries: Its properties as a dyestuff intermediate also lend themselves to applications in the textile industry and specialized printing inks, where it can contribute to colorfastness and vibrancy.

Why Choose a Trusted Manufacturer and Supplier?

When you are in the market to purchase Crystal Violet Lactone, selecting a reputable manufacturer and supplier is paramount. The performance of CVL in its end applications is highly dependent on its purity and consistency. Impurities can lead to:

  • Inconsistent color development
  • Faded or dull images
  • Reduced print stability
  • Production issues during formulation
