Cas no 74761-42-5 (MOC-Val-OH)
MOC-Val-OH is a protected valine derivative commonly used in peptide synthesis. The methoxycarbonyl (MOC) group serves as an N-terminal protecting group, offering stability under acidic and basic conditions while remaining selectively removable under mild conditions. This compound is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase methodologies, where it ensures high coupling efficiency and minimizes side reactions. Its compatibility with standard Fmoc/t-Bu strategies makes it a versatile building block for constructing complex peptides. MOC-Val-OH is characterized by its high purity and consistent performance, making it a reliable choice for researchers in pharmaceutical and biochemical applications.
