Product Overview

tert-Butyl Alcohol 99% AR/ACS (CAS No. 75-65-0) is analytical reagent 2-methylpropan-2-ol, a tertiary alcohol that combines complete tert-butyl substitution at the carbinol centre with broad compatibility in mixed aqueous–organic solvent systems. Its relatively accessible solid–liquid transition and ability to dissolve compounds spanning different polarity ranges also make it useful in selected physical-chemistry measurements.

The AR/ACS grade is intended for precise analytical work of a general nature, reagent preparation and laboratory quality-control procedures requiring ACS-defined reagent characteristics.

Typical Applications

• Preparation of analytical reagent, sample and blank solutions where tert-butanol is specified.
• Solvent and co-solvent in mixed aqueous–organic analytical systems.
• Cryoscopic determination of molar mass in suitable physical-chemistry procedures.
• Solubility, phase-equilibrium and solvent-interaction studies.
• Preparation of non-certified tert-butanol working solutions for method development.
• Laboratory quality-control procedures requiring AR/ACS-grade tert-butyl alcohol.
