Description supplémentaire:

All-trans-Retinal (Retinaldehyde, RAL), also called vitamin A aldehyde, is an oxidized retinol derivative (CAS 116-31-4, C20H28O, MW 284.44, melting point 61-63°C) produced via oxidative cleavage of beta-carotene, which is then reduced to retinol and oxidized to retinoic acid. Supplied as yellow crystals or powder at minimum 98% purity by HPLC, it serves as an intermediate metabolite of natural retinoic acid with similar bioactivity but significantly better skin tolerance — retinoic acid's broad dermatological uses have been limited by the local irritation that retinal avoids.
