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.
The longer and hence more lipophilic the fatty acid ester, the slower the release from the depot, the lower the peak estradiol levels, and the longer the duration. [274] [10] [265] The duration of estradiol esters in oil solution by intramuscular injection is dose-dependent. [282]
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.
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.
Such reactions require an acid catalyst such as hydrogen fluoride. tert-Butyl alcohol and isobutyl alcohol can also be used in place of isobutene. Globally, several million kilograms are produced annually. [1] Pivalic acid is also economically recovered as a byproduct from the production of semisynthetic penicillins like ampicillin and amoxycillin.
An ester of carboxylic acid.R stands for any group (organic or inorganic) and R′ stands for 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).
Alcohol oxidation is a collection of oxidation reactions in organic chemistry that convert alcohols to aldehydes, ketones, carboxylic acids, and esters. The reaction mainly applies to primary and secondary alcohols.
