Levocarnitine EP Impurity D (E and Z isomer) serves as a critical reference standard for quality control in pharmaceutical manufacturing. It is chemically defined as the E/Z isomeric mixture of 3-hydroxy-4-(trimethylammonio)butanoate, typically associated with Levocarnitine degradation or synthesis byproducts. The molecular formula is C7H15NO3, with specific CAS numbers assigned to distinct isomers. This compound is essential for validating purity profiles under European Pharmacopoeia guidelines.
