Intermediate: A material produced during steps of the processing of an API that undergoes further molecular change or purification before it becomes an API. Intermediates may or may not be isolated. (Note: this guidance only addresses those intermediates produced after the point that a company has defined as the point at which the production of the API begins.)选自ICH Q7A GLOSSARY
看这个定义,作为中间体(固体或液体)会在后期还有相关的molecular change or purification操作,那么这样看来这个应该不能定义为intermediate,而应该定义为in-process material,不知道是否合适???
补充内容 (2016-10-5 21:31):
In-Process Material
Any material fabricated, compounded, blended, or derived by chemical reaction that is produced for, and used in, the preparation of the drug product.
