Key Properties
Thymol crystals extra pure is a naturally occurring phenolic monoterpene that is primarily derived from the oil of thyme (Thymus vulgaris). It is recognized for its antiseptic and preservative properties, making it a valuable compound in various applications, particularly in the pharmaceutical and cosmetic industries. With a high purity of 99%, this grade of thymol is suitable for sensitive formulations and research applications. Its unique chemical structure contributes to its effectiveness as a disinfectant and its characteristic thyme-like aroma, which is often utilized in flavoring and fragrance formulations.
Also known as 2-Isopropyl-5-methylphenol.
