Methotrexate EP Impurity C is a critical reference standard defined by the European Pharmacopoeia. It serves as an analytical marker for quality control in methotrexate synthesis, typically arising from side reactions during the condensation of 2,4-diamino-6-hydroxypyrimidine with phthalic anhydride derivatives. Its molecular formula is C19H15N7O4 and CAS number is 1084-34-8.
Strictly store under inert atmosphere at 2-8°C to prevent degradation. Handle with appropriate PPE due to potential cytotoxicity; avoid inhalation or skin contact during laboratory weighing and preparation.
