Crystal Violet Lactone (CVL), identified by CAS number 1552-42-7, is a specialty chemical that plays a vital role in various industrial applications, most notably in the creation of imaging and recording systems. As a leuco dye, CVL possesses the unique characteristic of being colorless in its latent form and developing intense color upon specific chemical or physical triggers. For professionals in material science and chemical manufacturing, understanding CVL’s properties and procurement channels is essential.

The typical form of Crystal Violet Lactone is a fine white powder, with a molecular formula of C26H29N3O2 and a molecular weight of 415.53. Its key feature is its heat and pressure sensitivity, combined with excellent oil solubility. This makes it an ideal candidate for incorporation into microcapsules used in carbonless copy paper. When pressure is applied, these microcapsules rupture, releasing the CVL. This released dye then reacts with an acid developer, inducing a structural change that results in the formation of a brilliant blue-violet color. This process is fundamental to how carbonless copy paper functions, enabling multi-part forms to create copies without the need for carbon inserts.

The technical specifications of CVL are critical for its performance. A minimum assay of 96% is commonly required by manufacturers to ensure consistent color development and high chroma. The melting point, typically above 175°C, indicates the compound's thermal stability during processing and storage. When sourcing this chemical, it is important to work with manufacturers that provide detailed technical data and ensure product consistency batch after batch. Buyers often look to purchase Crystal Violet Lactone from established suppliers who can offer both quality and reliability.

Many industries rely on sourcing high-purity organic intermediates from global markets. China has become a significant hub for chemical manufacturing, offering competitive pricing for materials like Crystal Violet Lactone. Companies such as NINGBO INNO PHARMCHEM CO.,LTD. focus on producing and supplying chemicals like CVL, catering to the specific needs of industries requiring advanced materials for imaging and printing. When you decide to buy Crystal Violet Lactone, consider the supplier's commitment to quality control, their production capacity, and their ability to provide necessary documentation, including safety data sheets and certificates of analysis.

In conclusion, Crystal Violet Lactone (CAS 1552-42-7) is an indispensable component for sophisticated imaging solutions. By understanding its technical attributes and partnering with reliable manufacturers and suppliers, businesses can effectively leverage the capabilities of this versatile leuco dye to create high-performance products.
