Tosyl Azide CAS 941-55-9

Tosyl azide (CAS:941-55-9) is an important organic raw materials.

Its main applications including:

1. Core diazotization reagent for fine organic and pharmaceutical intermediate synthesis.
2. Tosyl azide is applied in click chemistry to construct various nitrogen-containing heterocyclic skeletons.
3. Tosyl azide is used in chemical research for preparation of diazo substrates for cyclization and insertion reactions.

1. Store airtight below 20°C in dark dry cabinet to prevent photolysis and gradual decomposition of azide groups.
2. Strictly avoid friction, impact, heating and open flame to eliminate explosion risk of azide compound.
3. Store separately from heavy metal salts, strong acids and reducing agents to prevent violent side reactions.

1. Efficient diazo transfer reagent widely applicable for converting active methylene groups into diazo compounds.
2. Moderate reaction activity with good solubility in common anhydrous organic solvents for lab synthesis.
3. Stable at low temperature before activation and easy post-reaction separation of sulfonyl byproducts.

1. Prevent inhalation of solid dust; wear explosion-proof goggles, dust mask and solvent-resistant gloves during operation.
2. Never ingest the substance; rinse splashed eyes and skin with large amount of cold running water at once.
3. Dispose waste solids and filtrate strictly following rules for explosive azide hazardous chemicals.
