4,5-Dihydro-5α-methoxy D-(-)-Norgestrel Discontinued - Introduction

4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued, also known as 4,5-dihydro-5α-methoxy D-(-)-levonorgestrel discontinuation, it is a hormonal impurity. The following is a description of its nature, use, preparation and safety information:

Nature:
4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued is a by-product of levonorgestrel, a white to off-white crystalline solid. Its chemical structure is C21H28O2 and its molecular weight is 312.45. 4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued is present in the preparation of levonorgestrel.

Use:
4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued is usually a by-product in the preparation of levonorgestrel, and its presence may affect the purity and quality of levonorgestrel. Levonorgestrel is a synthetic hormonal contraceptive used in women for contraception and regulation of the menstrual cycle.

Preparation Method:
4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued is generated through a multi-step reaction in the process of synthesizing levonorgestrel. Specific synthetic methods may include steps such as esterification, reduction, hydroxyl protection, and etherification.

Safety Information:
specific information on the safety and toxicity of 4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued is limited because it is a by-product of levonorgestrel, and is considered to be a lower level of impurities. However, when using or handling 4,5-dihydro-5α-methoxy D-(-)-Norgestrel Discontinued, it is still necessary to follow laboratory safety procedures and control according to relevant regulations. If necessary, it is recommended to consult relevant professional institutions or institutions engaged in relevant research to obtain more accurate and detailed safety information.
