INFRARED REFERENCE SPECTRA - JP XVIII Infrared Reference Spectra 2179-2187

Oct 12, 2026

Upload by sagouaw

Infrared reference spectra are presented using Fourier-transform infrared spectrophotometers under conditions defined in individual monographs. The spectra are organized with wave numbers (cm－1) on the horizontal axis and transmittance (z) on the vertical axis, and a polystyrene spectrum is included for reference. The document lists multiple JP XVIII entries for drug substances and specifies that JP drugs must be tested according to the relevant monographs, General Notices, General Rules, and General Tests for conformity to the Japanese Pharmacopoeia.
