General Information
Ormeloxifene Impurities and Ormeloxifene
Daicel Pharma offers Ormeloxifene Impurity standards, including 7-Desmethyl Impurity and CIS CENTCHROMAN HCl. They determine the quality, stability, and safety of Ormeloxifene, an active pharmaceutical ingredient (API). Daicel Pharma can synthesize custom Ormeloxifene impurities and distribute them across the world.
Ormeloxifene [CAS: 31477-60-8] is a nonsteroidal contraceptive medication for selective antiestrogen that
manages dysfunctional uterine bleeding.
Ormeloxifene: Use and Commercial Availability
Ormeloxifene is a nonsteroidal medication that selectively inhibits estrogen. It effectively blocks estrogen and treats mastalgia and many tiny fibroadenomas. It is available under the tradename Centchroman.
Ormeloxifen Structure and Mechanism of Action 
The chemical name of Ormeloxifene is rel-1-[2-[4-[(3R,4R)-3,4-Dihydro-7-methoxy-2,2-dimethyl-3-phenyl-2H-1-benzopyran-4-yl]phenoxy]ethyl]pyrrolidine. Its chemical formula is C30H35NO3, and its molecular weight is approximately 459.6 g/mol.
Ormeloxifene prevents embryo implantation and endometrial receptivity.
Ormeloxifene Impurities and Synthesis
Ormeloxifene is a selective estrogen receptor modulator (SERM) used as a contraceptive for treating abnormal uterine bleeding. During the synthesis1 of Ormeloxifene, impurities form through various processes. They may arise from incomplete reactions, side reactions, or contaminants in the starting materials or reagents. Additionally, impurities can occur during the storage or degradation of Ormeloxifene.
Daicel Pharma offers a Certificate of Analysis (CoA) for Ormeloxifene impurity standards, including the 7-Desmethyl Impurity and CIS CENTCHROMAN HCl. Our CoA is from a cGMP-certified analytical facility and contains comprehensive characterization information such as 1H NMR, 13C NMR, IR, MASS, and HPLC purity. Additional characterization information, including 13C-DEPT, can be provided upon request. At Daicel Pharma, our team of experts specializes in synthesizing Ormeloxifene impurities.
