According to some authors, organyl derivatives of acidic hydrogen of other acids are esters as well (e.g. amides), but not according to the IUPAC. [ 1 ] An example of an ester formation is the substitution reaction between a carboxylic acid ( R−C(=O)−OH ) and an alcohol (R'OH), forming an ester ( R−C(=O)−O−R' ), where R and R′ are ...
An ester of a carboxylic acid.R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group.. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). [1]
In organic chemistry and biochemistry esters are the functional group (R'-COOR") consisting of an organic radical united with the residue of any oxygen acid, either organic or inorganic. An ester is a product of the reaction of an acid (usually organic) and an alcohol (the hydrogen of the acid R-COOH is replaced by an alkyl group R").
This is a list of estrogen esters, or ester prodrugs of estrogens. It includes esters, as well as ethers , of steroidal estrogens like estradiol , estrone , and estriol and of nonsteroidal estrogens like the stilbestrols diethylstilbestrol and hexestrol .

This is a complete list of estrogens and formulations that are approved by the FDA Tooltip Food and Drug Administration and available in the United States. Estrogens are used as hormonal contraceptives , in hormone replacement therapy , and in the treatment of gynecological disorders .
The most common vehicles for injections of steroids and steroid esters are oil solutions, but aqueous solutions, aqueous suspensions, and emulsions have also been used. [11] [additional citation(s) needed] The durations of estrogen esters are not prolonged if they are given orally, vaginally, or by intravenous injection. [11]
