Description
- General description: 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.[1]
- Application: Letrozole may be used as a pharmaceutical reference standard for the determination of the analyte in biological/environmental samples[1][2] and pharmaceutical formulations[3] by various chromatography techniques.
- Biochem/physiol Actions: Letrozole is a third generation nonsteroidal aromatase inhibitor. It is a competitive inhibitor of the aromatase enzyme system and thus inhibits the conversion of androgens to estrogens. Letrozole inhibits the aromatase enzyme by competitively binding to the heme of the cytochrome P450 subunit of the enzyme, resulting in a reduction of estrogen biosynthesis in all tissues.
- Analysis Note: These secondary standards offer multi-traceability to the USP, EP and BP primary standards, where they are available.
- Other Notes: 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.
