在化學與制藥領域，“starting material”（起始物料）是指用于合成目标産物或活性藥物成分（API）的原始化學物質或化合物。它是整個生産流程的起點，直接影響最終産品的質量與安全性。例如，在阿司匹林合成中，水楊酸和乙酸酐通常被定義為起始物料。
這一概念在藥品監管中尤為重要。根據國際人用藥品注冊技術協調會（ICH）的規定，起始物料需滿足明确的化學特性與純度标準，且其選擇需确保後續反應步驟能有效控制雜質生成。美國FDA在《藥品生産質量管理規範》（cGMP）中同樣要求企業建立起始物料的完整溯源體系。
在材料科學領域，起始物料可能包括金屬氧化物、聚合物單體等基礎成分。例如钛酸鋇陶瓷的制備常以碳酸鋇和二氧化钛為起始物料。學術界普遍通過傅裡葉變換紅外光譜（FTIR）和高效液相色譜（HPLC）等技術對起始物料進行表征分析。
"Starting Material"（起始物料）是化學、制藥及工業生産中的常用術語，其核心含義和具體應用如下：
如需進一步了解具體行業的應用規範，可參考制藥領域的ICH Q7 指南或相關生産标準文件。
