N-Acetil-L-Arginina (CAS 155-84-0) se presenta frecuentemente como impureza en procesos de acetilación de aminoácidos y síntesis peptídica | alterando el perfil de pureza del material final. Su presencia puede afectar la cuantificación y la actividad biológica del lote si no se controla. La identificación y cuantificación se realiza mediante técnicas analíticas estándar como HPLC con detección UV | LC-MS y RMN para confirmar estructura y masa. Estrategias de control incluyen optimización de condiciones de reacción | purificación por cromatografía reversa o intercambio iónico y establecimiento de límites de especificación en el control de calidad. La monitorización periódica es clave para cumplimiento regulatorio.
