General description
用于质量控制的制药二级标准品，为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。吡啶是一种杂环化合物，是有机和无机化学中常用的溶剂。其弱碱性使其在酸碱反应中充当质子受体，并与强酸形成盐。在醇的酰化反应中，吡啶可作为亲核催化剂。
Application
这些二级标准品是合格的认证标准物质（CRM）。它们适用于多种分析应用，包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。
Analysis Note
这些二级标准品可追溯至USP、EP和BP一级标准品。
Other Notes
想要查看本品的检验报告示例，请在下框中输入LRAC0263。这只是一个示例证书，可能与您收到的批次不符。
该认证标准物质（CRM）根据ISO 17034 和 ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在检验报告上找到。

Allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGlu5) have exciting potential as therapeutic agents for multiple brain disorders. Translational studies with mGlu5 modulators have relied on mGlu5 allosteric site positron emission tomography (PET) radioligands to assess receptor occupancy
