Description

Estradiol-16 is a specific isomer of estradiol, a key steroidal estrogen. This compound is of significant interest in pharmaceutical research and development, particularly for its role in hormone-related studies and as a potential synthetic intermediate. It is primarily utilized by research institutions and pharmaceutical companies engaged in the development of steroidal drugs and biochemical assays. Our supply of Estradiol-16 CAS NO 1090-04-6 is characterized by high purity and reliable consistency to meet stringent research and production requirements.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of more complex steroidal hormones and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a reference standard or reagent in laboratory studies investigating estrogen receptor binding, metabolism, and hormonal pathways.
• Analytical Standard: Employed in quality control laboratories for method development and calibration in chromatographic analyses (e.g., HPLC, GC) of estrogenic compounds.
• Academic Research: Utilized in university and institutional research projects focused on endocrinology, developmental biology, and cancer studies.
