p-Nitrobenzyl 2-diazoacetoacetate (PNBDAA) is a specialized photo-cleavable protecting group reagent. Its molecular formula is C11H9N3O6 with CAS 75840-99-2. This compound undergoes rapid cleavage upon UV irradiation, facilitating precise release of linked moieties in synthetic chemistry.
Store at -20°C under inert atmosphere to prevent premature decomposition. Avoid direct exposure to UV light during handling. Use appropriate PPE as diazo compounds may exhibit toxicity and sensitization risks.
