关于中间体与中间物质的英文描述区别
QA
ICH中定义:中间体是原料药生产过程产生的、须经进一步分子变化或者纯化才能成为原料药的物料。那么发酵产品的发酵液算不算中间体,用英文表示是否跟中间体一样(Intermediate)?

FDA指南Guidance for Industry Drug Substance Chemistry, Manufacturing, and Controls Information的Glossary中讲到:

In Situ Intermediate: An intermediate that is not isolated. It is normally, but not necessarily, in solution

发酵液就属于这种情况,英文表示为In Situ Intermediate
