GRADE & PURITY Anhydrous Grade ? Anhydrous grade — water removed and packaged dry for moisture-sensitive chemistry. Use in reactions where even trace water would interfere or quench. Reagent Grade ? General reagent-grade purity suitable for most laboratory work. Use as a dependable default when no specific higher grade is required. High-purity ? High-purity grade with substantially reduced impurity levels. Use when trace contaminants would interfere with your measurement or process. ≥99%
