Conversely, intramuscular injections of estradiol esters in oil solution have durations of days to months, depending on the ester administered. [265] Following a single 4 or 5 mg intramuscular injection in oil solution, peak estradiol levels are about 950 pg/mL with estradiol benzoate after 2 days, 400 to 650 pg/mL with estradiol valerate after ...
Estradiol plus the fatty acid valeric acid (valerate) equals estradiol valerate, a C17β ester of estradiol. [107] Estradiol valerate is a synthetic estrane steroid and the C17β valerate (pentanoate) fatty acid ester of estradiol. [23] [24] It is also known as estradiol 17β-valerate or as estra-1,3,5(10)-triene-3,17β-diol 17β-pentanoate.
Valeric acid or pentanoic acid is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 (CH 2) 3 COOH. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor . It is found in the perennial flowering plant Valeriana officinalis , from which it gets its name.
Polyestradiol phosphate, a polymer of estradiol phosphate, the C17β phosphoric acid ester of estradiol. It has on average of 13 repeat units. Estradiol esters have an ester moiety, usually a straight-chain fatty acid (e.g., valeric acid) or an aromatic fatty acid (e.g., benzoic acid), attached at the C3 and/or C17β positions of the steroid ...
Methyl pentanoate, commonly known as methyl valerate, is the methyl ester of pentanoic acid (valeric acid) with a fruity odor. Methyl pentanoate is commonly used in fragrances, beauty care, soap, laundry detergents at levels of 0.1–1%. In a very pure form (greater than 99.5%) it is used as a plasticizer in the manufacture of plastics.

Transesterification is the process of exchanging the organic functional group R″ of an ester with the organic group R' of an alcohol. These reactions are often catalyzed by the addition of an acid or base catalyst. [1] Strong acids catalyze the reaction by donating a proton to the carbonyl group, thus making it a more potent electrophile.
The saccharide products can be recovered from the lactone into water solution by antisolvent addition of salt or liquid carbon dioxide. The product can be used as feedstock for producing furans or ethanol at high yield, while the gamma-valerolactone is returned to the catalytic cycle.
