1-Benzyl-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-histidine(CAS: 84030-19-3)

1-Benzyl-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-histidine is a white to off-white crystalline solid with a molecular weight of approximately 637.56 g/mol. It has a low solubility in water (less than 1 mg/mL at 25°C) and is more soluble in organic solvents such as methanol and acetonitrile. The compound shows moderate reactivity towards nucleophiles and can be used in various chemical reactions, particularly in peptide synthesis and drug development.

1-Benzyl-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-histidine is synthesized using solid-phase peptide synthesis (SPPS) techniques. The synthesis involves coupling the 9-fluorenylmethoxycarbonyl (Fmoc) protected histidine with the benzyl ester, followed by removal of the Fmoc group. Commonly used conditions include the use of coupling agents like HATU and DIPEA in an N,N-dimethylformamide (DMF) solvent. The overall yield is typically around 70-85%, depending on the purity of starting materials and reaction conditions.

1-Benzyl-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-histidine is primarily used in the pharmaceutical industry for drug development and peptide synthesis. It is also relevant to the polymer industry for the synthesis of functional polymers and in the semiconductor industry for the development of organic electronic materials. Its use in sensors and as a reagent in other chemical processes is also growing due to its unique chemical properties.

When handling 1-Benzyl-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-histidine, it is important to follow safety guidelines. Personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. Work should be conducted in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up using appropriate solvents and protective gear. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and follow all laboratory safety protocols.
