Loxoprofen, a prodrug-type nonsteroidal anti-inflammatory drug (NSAID), exerts analgesic, anti-inflammatory, and antipyretic effects via metabolic conversion to its active trans-OH form. In pharmaceutical R&D and quality control, impurity reference standards are critical for ensuring drug safety and efficacy. This documentation provides high-purity Loxoprofen impurity reference standards, covering major degradation products and process-related impurities (e.g., Impurity A, B, C), suitable for forced degradation studies, analytical method validation, and ICH Q3A/Q3B compliance.
