1-{[(p-nitrobenzyl)oxy]carbonyl}-1H-benzotriazole(CAS: 86832-06-6)

1-{[(p-nitrobenzyl)oxy]carbonyl}-1H-benzotriazole is a white to off-white crystalline solid with a molecular weight of approximately 395.14 g/mol. It is relatively soluble in organic solvents such as dichloromethane and acetone, but poorly soluble in water. This compound exhibits moderate reactivity, particularly towards nucleophiles, and is commonly used in peptide coupling reactions. It is stable under normal storage conditions but should be protected from moisture and light.

1-{[(p-nitrobenzyl)oxy]carbonyl}-1H-benzotriazole is typically synthesized through the condensation of p-nitrobenzyl chloroformate with 1H-benzotriazole. This reaction proceeds in the presence of a base such as triethylamine, with excellent yield and selectivity. The process is carried out in anhydrous organic solvents like dichloromethane at ambient temperature.

1-{[(p-nitrobenzyl)oxy]carbonyl}-1H-benzotriazole is primarily used in the pharmaceutical and chemical industries for the synthesis of peptides and other bioactive molecules. It is also utilized in the semiconductor industry for the fabrication of organic thin-film transistors and sensors, where its reactivity and stability make it a valuable reagent.

When handling 1-{[(p-nitrobenzyl)oxy]carbonyl}-1H-benzotriazole, it is essential to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. This compound should be stored in a cool, dry place away from moisture and light. In case of spills, they should be cleaned up using appropriate methods, and any contaminated materials should be disposed of properly as per local regulations.
