Stable Physical Form: The product is typically available as white to off-white granules or powder, providing a stable and easy-to-handle solid form suitable for various processing and storage conditions.
Versatile Solvent Compatibility: It offers excellent solubility in multiple organic solvents—including alcohol, benzene, toluene, and chloroform—making it highly adaptable for use in diverse chemical formulations and industrial applications.
Selective Solubility for Specialized Use: While it is hardly soluble in water, the product dissolves well in dilute alkali solutions, allowing for flexible application in systems where controlled solubility is needed.
Strong Hygroscopic Properties: Its ability to readily absorb moisture from the air can be advantageous in moisture-sensitive reactions or environments, provided proper handling and storage measures are used to maintain product quality.
5-Methyl-1H-benzotriazole CAS#136-85-6
The pure substance generally appears as white to off-white granules or powder, though its actual form may vary slightly depending on factors like purity. In terms of solubility, it is almost insoluble in water but dissolves well in organic solvents such as alcohol, benzene, toluene, and chloroform, and it is also soluble in dilute alkaline solutions. Additionally, it is hygroscopic and readily absorbs moisture from the surrounding air.
