This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
2,4,6-Trimethylbenzoyl chloride is used, in the presence of pyridine, to protect OH groups as mesitoate esters.
Solubility
Reacts slowly with water.
Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Recommended storage temperature: 2 - 8°C. Air and moisture sensitive. Store under nitrogen. Incompatible with strong oxidizing agent
