CAS:5-bromo-3-methylthiophene-2-carboxylic acid (5BmtCA) is a potential therapeutic that has been shown to have the same estrogenic activity as estradiol. It may be used for the treatment of osteoporosis and other conditions associated with estrogen deficiency, including resorption and bone loss. 5BmtCA is an amide with two phenyl groups at the C3 position, which are bioisosteres of the sulfur in estradiol. The substitutions on these phenyl groups can be changed to produce analogs with different properties. For example, 5BmtCA may be substituted with a ketone group at position C3 to produce the corresponding ketone analog 5BmtCK. This compound would be expected to have reduced bone resorption activity relative to 5BmtCA.Formula:C6H5BrO2SPurity:Min. 95%Color and Shape:PowderMolecular weight:221.07 g/mol2-Amino-6-tert-butyl-N-(4-chlorophenyl)-4,5,6,7-tetrahydro-1-benzothiophene-3-carboxamide
