药物晶型及多晶型研究一直是各制药企业研究的热门话题,目前用于药物晶型及多晶分析的方法主要有TRS、XRPD及NMR等等,本文章通过详细的实验及数据对了TRS、XRPD及NMR这三种技术在药物晶型分析方面,特别是低含量晶型分析方面的对比应用。Fast Non-Destructive Detection of Low Level Crystalline Forms in Amorphous Spray Dried Dispersion Using Transmission Raman Spectroscopy and Comparison to Solid-State NMR Spectroscopy
Simple Raman measurements of even ’off-theshelf’ organic materials illustrate that it is possible to differentiate between materials that differ by:• stereo isomer,• polymorphy,• pseudo polymorphy (due to water of hydration).
