Product Overview

Toluene 99.5% Specially Dried AR (CAS No. 108-88-3) is methylbenzene supplied in a specially dried form intended to reduce the amount of moisture introduced into non-aqueous analytical and preparative systems. Toluene itself is a non-polar aromatic solvent widely used for extraction, reaction media and solvent exchange, while reduced moisture can be important when water affects reagents, catalysts or moisture-sensitive equilibria.

The Specially Dried AR grade is intended for analytical and preparative procedures in which moisture introduced by the solvent affects reaction chemistry or sample integrity. It is particularly useful for water-sensitive reagent preparation, non-aqueous analytical work and moisture-conscious organic synthesis.

Typical Applications

• Preparation of moisture-sensitive non-aqueous reagent solutions.
• Solvent for water-sensitive analytical and preparative chemistry.
• Solvent exchange into reduced-moisture organic media.
• Extraction where minimised water contribution is important.
• Preparation of moisture-sensitive reaction mixtures and standards.
• Non-aqueous laboratory QC and reagent preparation.

Common Synonyms

• Methylbenzene
• Toluol
• Phenylmethane

Storage Conditions

Keep tightly closed and minimise exposure to humid air so that the reduced-moisture character is preserved. Prevent solvent and particulate contamination and promptly reseal after dispensing.
