About n-Fmoc-L-aspartic acid 4-benzyl ester, 98%+

Listed under CAS 86060-84-6, n-Fmoc-L-aspartic acid 4-benzyl ester is a protected amino acid available from Vaqora Chemicals in Biochemistry grade at a purity of ≥98%. Its molecular formula is C26H23NO6 and its molecular weight is 445.5 g/mol. Systematically, it is named (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-4-oxo-4-phenylmethoxybutanoic acid. It is also known as N-(9-Fluorenylmethoxycarbonyl)-L-isoleucine or Fmoc-L-isoleucine.

The material typically appears as white to almost white powder or crystals. Literature values give a melting point of 125-129 °C. Store sealed in a dry, well-ventilated location away from incompatible materials. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span solid-phase peptide synthesis (SPPS), peptide drug discovery and medicinal chemistry. Typical end-use sectors are academic and industrial research and diagnostics and biotechnology.

Standard pack sizes are 1 g, 5 g, 10 g and 25 g, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
