About L-Centchroman

Vaqora Chemicals supplies L-Centchroman, a high-purity reference standard of Ormeloxifene registered under CAS number 78994-23-7. Its molecular formula is C30H35NO3 and its molecular weight is 457.6 g/mol. The IUPAC name is 1-[2-[4-[(3R,4R)-7-methoxy-2,2-dimethyl-3-phenyl-3,4-dihydrochromen-4-yl]phenoxy]ethyl]pyrrolidine. Common synonyms include Levormeloxifene and Ormeloxifene.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

As a reference sample of Ormeloxifene, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
