Overview
Benzhydrol powder, chemically known as diphenylmethanol, is an organic compound with the formula (C6H5)2CHOH. It appears as a white crystalline solid and is widely used in industrial and laboratory settings. As a secondary alcohol, benzhydrol serves as a versatile intermediate in organic synthesis. Its two phenyl groups make it useful for creating more complex molecular structures, particularly in pharmaceutical manufacturing.
Physical and Chemical Properties
Benzhydrol powder has a molecular weight of 184.24 g/mol and melts between 65-68°C. It's soluble in organic solvents like ethanol and ether but has limited water solubility. The compound exhibits typical alcohol reactivity, capable of undergoing oxidation to form benzophenone. Its stability under normal conditions makes it suitable for various chemical processes without requiring special handling beyond standard precautions.
Main Applications
In the pharmaceutical industry, benzhydrol serves as a key intermediate for antihistamines and other active pharmaceutical ingredients. It's also used in fragrance compounds, contributing to floral notes. The chemical finds application in polymer production as a chain transfer agent and in UV stabilizers for plastics. Some specialty chemical formulations utilize benzhydrol for its mild reducing properties in controlled reactions.
Safety and Storage
While benzhydrol isn't classified as highly hazardous, proper safety measures should be followed. Use gloves and eye protection when handling, and avoid creating dust that could be inhaled. Store in tightly sealed containers away from oxidizers and strong acids. The powder is stable at room temperature but should be protected from moisture to prevent clumping or decomposition over time.
B2B Procurement Guide
When sourcing benzhydrol powder, request certificates of analysis confirming purity (typically 98% or higher). Bulk pharmaceutical-grade material may command premium pricing. Consider supplier reliability, batch consistency, and shipping conditions. Technical-grade material suits most industrial applications, while pharmaceutical applications require higher purity standards and additional documentation.
