Product Overview
iso-Butanol 99% AR is a high-purity analytical reagent-grade solvent designed for critical laboratory applications. With a minimum assay of 99%, this colorless liquid ensures reliable performance in organic synthesis, extractions, and chromatographic techniques. Its low water content (<0.1%) minimizes interference in sensitive reactions, while the AR grade guarantees consistent batch-to-batch quality. The solvent’s moderate boiling point (107°C) and miscibility with common organic solvents make it versatile for diverse lab protocols. Packaged in amber glass bottles to prevent photodegradation, this iso-Butanol variant meets stringent purity standards, including heavy metal content below 5 ppm. The reagent is stabilized to resist oxidation, extending shelf life without compromising purity. Its controlled evaporation rate enhances precision in volumetric applications, while the absence of residual aldehydes or ketones ensures clean reaction profiles. Compatible with most lab glassware and PTFE-sealed containers, this solvent maintains integrity across temperature ranges from -20°C to 40°C.
FAQs
1. What is the water content specification for this iso-Butanol?
The water content is maintained below 0.1% by weight, ensuring minimal interference in moisture-sensitive reactions.
2. Can this solvent be used with HPLC systems?
Yes, the 99% AR grade purity makes it suitable for HPLC applications when filtered through a 0.22µm membrane prior to use.
3. What materials are incompatible with iso-Butanol storage?
Avoid storing in containers made of natural rubber or certain plastics like polyethylene, as these may degrade over time.
4. How does the AR grade differ from technical grade?
AR grade undergoes additional purification steps to remove trace metals and organic impurities, resulting in higher consistency for analytical work.
5. What’s the typical shelf life under proper storage conditions?
When stored in tightly sealed original containers at room temperature, the shelf life is 24 months from the date of manufacture.
