For chemical formulators working with advanced materials, understanding the intrinsic properties and reliable sourcing of key ingredients is fundamental. Psoralen (CAS 66-97-7) is one such compound, recognized for its specific photochemical characteristics that lend themselves to specialized applications, particularly within the electronics industry. This article aims to guide formulators on what to look for when purchasing Psoralen and how to establish robust supply chains.

Psoralen is a crystalline solid with a defined molecular formula (C11H6O3) and molecular weight of approximately 186.16 g/mol. Its melting point, typically around 163-164°C, and its solubility in common organic solvents like ethyl acetate and acetone are important parameters for formulation development. The critical factor for many chemical applications, especially in photoresist formulations, is the purity of the Psoralen. High-purity grades, usually exceeding 98% or 99% as determined by HPLC, are essential to ensure consistent performance and to avoid unwanted side reactions or film defects. When formulators decide to buy Psoralen, they must carefully review the specifications provided by the supplier.

The primary commercial application for Psoralen lies in its use as an electronic chemical, particularly in the photoresist industry. Its photoactivity allows it to function effectively in lithographic processes, which are the backbone of semiconductor manufacturing. Formulators often seek a dependable Psoralen manufacturer that can consistently deliver materials meeting tight quality control standards. China has emerged as a significant global supplier for such specialized fine chemicals, offering competitive pricing and large-scale production capabilities. For businesses looking to purchase Psoralen in bulk, identifying a reputable Chinese supplier with a proven track record is a strategic advantage.

In addition to its electronic applications, Psoralen (CAS 66-97-7) also finds utility in various research settings as a photochemical tool. This dual application profile means that formulators might also encounter Psoralen in research-grade materials. When evaluating a Psoralen chemical supplier, it’s important to consider their ability to cater to different order sizes, from small R&D quantities to industrial-scale volumes. Companies interested in securing a stable supply should investigate potential partners thoroughly, looking for clear communication, strong technical support, and timely delivery. If your formulation needs require Psoralen, ensure you buy Psoralen from a manufacturer committed to quality and reliability.
