Additional information

According to Guidance on information requirements and chemical safety assessment, chapter R.7a: Endpoint specific guidance (R.7.1.9.4), the flash point is only relevant to liquids and low melting point solids. The determination of the flash point is not required as L-tryptophan is a solid at standard conditions with a high melting point (ca. 290°C).
