CAS:10540-29-1 is the Chemical Abstracts Service (CAS) registry number for tamoxifen, a well-known medication primarily used in the treatment and prevention of breast cancer. CAS numbers are unique numerical identifiers assigned to chemical substances by the Chemical Abstracts Service, a division of the American Chemical Society. These numbers are used globally to provide a standardized reference for chemicals, allowing for precise identification across various scientific and regulatory contexts.
The specific CAS number 10540-29-1 corresponds to tamoxifen's chemical structure and formulation. Tamoxifen belongs to a class of drugs known as selective estrogen receptor modulators (SERMs), which interact with estrogen receptors in the body. By binding to these receptors, tamoxifen can block the effects of estrogen in breast tissue, helping to slow or prevent the growth of estrogen receptor-positive (ER+) breast cancers.
The use of CAS numbers like 10540-29-1 is critical in the pharmaceutical and chemical industries because it eliminates ambiguity. For example, different names, trade names, or synonyms may be used to describe the same chemical compound in different countries or fields, but the CAS number remains a consistent identifier. This is especially important in research, where the precise identification of substances is essential for reproducibility and accurate communication.
CAS numbers also play a crucial role in regulatory processes. Governments and international agencies rely on these identifiers to regulate the manufacture, distribution, and use of chemicals. In the case of tamoxifen, the CAS number 10540-29-1 ensures that the correct compound is referenced in legal and safety documentation, clinical trials, and pharmaceutical production.
In summary, CAS:10540-29-1 serves as the unique identifier for tamoxifen, ensuring consistency and accuracy in scientific, regulatory, and industrial contexts. This number is essential for the clear and precise communication of information related to tamoxifen and its uses.
