NovaBioX® CVL-96
(Crystal violet lactone)
Chemical Name: Crystal violet lactone
CAS No.: 1552-42-7
MF: C26H29N3O2
MW: 415.53
Molecular structure：
Crystal Violet Lactone is a key colorless dye, which belongs to the triphenylmethane phthalide series. CVL exhibits excellent light resistance and reversible thermal response. It is widely used in the manufacturing of pressure-sensitive and thermal-sensitive recording materials. In terms of thermal paper applications, CVL offers high color density, fast imaging speed, and good stability. It is a high-performance, low-toxicity leuco dye and has a good application prospect.

Q1: What are the main applications of Crystal Violet Lactone?
A: Crystal Violet Lactone is commonly used in thermal paper, carbonless copy paper, thermal labels, point-of-sale receipt paper and other functional recording materials.
Q2. Why is Crystal Violet Lactone used in carbonless copy paper?
A: In carbonless copy paper systems, Crystal Violet Lactone is encapsulated in microcapsules. When pressure breaks the capsules, the dye reacts with a developer coating to generate a permanent image.
Q3: What are the proper safety, storage, and handling guidelines for bulk CVL powder?
A: Bulk Crystal Violet Lactone should be stored in a cool, completely dry, and well-ventilated warehouse below 30℃. The containers must be kept tightly locked to protect the powder from acidic vapors and direct ultraviolet (UV) light, which can trigger premature oxidation. When handling the powder, workers should wear standard dust masks and gloves to avoid eye irritation or skin staining. Under these controlled environments, it has a shelf life of 24 months.
Q4: Where can I source high-purity Crystal Violet Lactone?
A: You can source high-purity commercial-grade Crystal Violet Lactone directly from specialized B2B chemical manufacturing platforms and suppliers like Sinocurechem. Our brand NovaBioX® CVL-96 guarantees an HPLC purity of ≥98.5% and minimal volatile residues.
