|original material;起始物料，原始材料；原材料
在化学与制药领域，“starting material”（起始物料）是指用于合成目标产物或活性药物成分（API）的原始化学物质或化合物。它是整个生产流程的起点，直接影响最终产品的质量与安全性。例如，在阿司匹林合成中，水杨酸和乙酸酐通常被定义为起始物料。
这一概念在药品监管中尤为重要。根据国际人用药品注册技术协调会（ICH）的规定，起始物料需满足明确的化学特性与纯度标准，且其选择需确保后续反应步骤能有效控制杂质生成。美国FDA在《药品生产质量管理规范》（cGMP）中同样要求企业建立起始物料的完整溯源体系。
在材料科学领域，起始物料可能包括金属氧化物、聚合物单体等基础成分。例如钛酸钡陶瓷的制备常以碳酸钡和二氧化钛为起始物料。学术界普遍通过傅里叶变换红外光谱（FTIR）和高效液相色谱（HPLC）等技术对起始物料进行表征分析。
"Starting Material"（起始物料）是化学、制药及工业生产中的常用术语，其核心含义和具体应用如下：
如需进一步了解具体行业的应用规范，可参考制药领域的ICH Q7 指南或相关生产标准文件。
