Having reached Step 4 of the ICH Process at the ICH Steering Committee meeting on 17 July 1997, this Guideline is recommended for adoption to the three regulatory parties to ICH 1. INTRODUCTION The objective of this guideline is to recommend acceptable amounts for residual solvents in pharmaceuticals for the safety of the patient.

This guideline deals with impurities (organic, inorganic and residual solvents) in new active substances and defines limits as of which impurities must be identified or qualified.

The ICH Q3A guideline provides a framework for establishing the reporting thresholds, such as qualification thresholds and identification thresholds for impurities in drug substances.
