4 - Nitrobenzyl chloroformate is often used as a protecting group in organic synthesis. 4-Nitrobenzyl chloroformate CAS 4457-32-3 can be used to protect amino groups, for example. After protecting the amino group, other reactions can be carried out on the molecule without affecting the amino functionality. Later, the protecting group can be removed under specific conditions to reveal the original amino group.
Packed in 25 kg per drum or based on customers' requirements.
1. Temperature
Keep 4-Nitrobenzyl chloroformate CAS 4457-32-3 in a cold place, preferably around 2 - 8°C (36 - 46°F). Lower temperatures help slow down any decomposition reactions that might occur over time.
2. Sealed Container
Store 4-Nitrobenzyl chloroformate in an airtight container. This is crucial because it's sensitive to moisture. Water can react with the chloroformate group, so preventing moisture from getting in preserves its integrity.
3. Away from Light
Although it's not highly light - sensitive, storing 4-Nitrobenzyl chloroformate CAS 4457-32-3 in the dark or in a light - resistant container is a good idea to maintain its stability.
4. Separation from Incompatible Substances
Avoid storing 4-Nitrobenzyl chloroformate near strong bases, nucleophiles, or substances that can react with the chloroformate or nitro groups.
