一般描述
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Letrozole is used for the treatment of breast cancer in hormone-dependent postmenopausal patients. The drug works by blocking the synthesis of estrogen, a causative agent for cancer.
应用
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Letrozole may be used as a pharmaceutical reference standard for the determination of the analyte in biological/environmental samples and pharmaceutical formulations by various chromatography techniques.
生化/生理作用
来曲唑是第三代非甾体芳香酶抑制剂。 它是芳香酶系统的竞争性抑制剂，因此可抑制雄激素向雌激素转化。来曲唑通过竞争性结合到该酶的细胞色素P450亚基的血红素上而抑制芳香酶，导致所有组织中雌激素的生物合成减少。
分析说明
These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
其他说明
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
