Sodium isobutoxide is an alkoxide of isobutanol. It is used in organic chemistry for the synthesis of isobutyl ethers.

Decoquinate is a quinolone derivative that is used in the control of coccidiosis in domestic animals. Decoquinate treats and prevents coccidiosis in chickens, cattle, goats, sheep, etc. Decoquinate acts on sporozoites development and prevents their penetration of the gut epithelium. Decoquinate inhibits mitochondrial respiration and electron transport in Eimeria.

Esculin (Esculoside), a coumarin compound derived from the horse chestnut and the traditional Chinese herbs such as Cortex Fraxini, has long been used for treating inflammatory and vascular diseases. The main activities of Esculoside focus on capillary protection, as it improves capillary permeability and fragility. It is reported to inhibit catabolic enzymes such as hyaluronidase and collagenase, thus preserving the integrity of the perivascular connective tissue. Esculin has various biological activities including anti-oxidant activity, intestinal anti-inflammatory activity, anti-cancer activity and growth inhibition of human leukemia cells. Esculin inhibits lipid peroxidation and scavenges hydroxyl radicals in the rat liver and exerts anti-inflammatory activity in both carrageenan- and zymosan-induced paw edema in mice. Esculin has the gastroprotective effect in cold-restraint stress and pylorus ligation-induced ulcer models. Esculin is used in a microbiology laboratory to aid in the identification of bacterial species (especially Enterococci and Listeria).

Adenosine triphosphate (ATP) is an adenine nucleotide containing three phosphate groups esterified to the sugar moiety. Adenosine triphosphate is the energy source in living cells. In physiological conditions, the average concentration varies from 3150 mM in mammalian cells to 1500–1900 mM in human blood cells. Extracellular adenosine and adenosine triphosphate (ATP) are involved in biological processes including neurotransmission, muscle contraction, cardiac function, platelet function, vasodilatation, signal transduction and secretion in a variety of cell types. A large family of membrane-bound receptors mediates cell signalling by ATP and adenosine. These purinergic receptors ultimately determine the variety of effects induced by extracellular ATP and adenosine. ATP and adenosine have strong negative chronotropic and dromotropic effects on the mammalian heart. The sensitivity of the sinus node and the atrioventricular node to ATP and adenosine manifests pronounced variability among species. For more than three decades, ATP has been used routinely in Europe in the acute therapy of paroxysmal supraventricular tachycardia. ATPace™, an injectable formulation of adenosine 5′-triphosphate (ATP), was developed by Cordex Pharma, Inc. (Cordex) as a diagnostic and therapeutic drug for the management of cardiac bradyarrhythmias. Extracellular ATP exerts multiple effects in various cell types by activating cell-surface receptors known as P2 receptors. In the heart, ATP suppresses the automaticity of cardiac pacemakers and atrioventricular (AV) nodal conduction via adenosine, the product of its degradation by ecto-enzymes, as well as by triggering a cardio-cardiac vagal reflex. ATP, given as a rapid intravenous bolus injection, has been used since the late 1940s as a highly effective and safe therapeutic agent for the acute termination of reentrant paroxysmal supraventricular tachycardia (PSVT) involving the AV node. In addition, preliminary studies have shown that ATP can also be used as a diagnostic agent for the identification of several cardiac disorders including sinus node dysfunction (sick sinus syndrome), dual AV nodal pathways, long QT syndrome, and bradycardic syncope. The US Food and Drug Administration has approved Cordex formulation for ATP as an Investigational New Drug and two pathways for its marketing approval; one therapeutic, i.e., acute termination of paroxysmal PSVT, and the other diagnostic, i.e., the identification of patients with bradycardic syncope who can benefit from pacemaker therapy. However later ATPace development for the treatment of bradycardia and paroxysmal supraventricular tachycardia was discontinued.

Butyl stearate is an ester of stearic acid and butanol. It is used in the cosmetic industry as a plasticizer in nail varnishes, emollient and skin conditioning agent in personal care formulations, as a masking agent in fragrances. In the food industry, it is used as a flavoring agent and as a defoaming agent in processing beet sugar and yeast.

Benzophenone is the organic compound. It is a flavouring agent evaluated as safe at current levels of intake by joint FAO/WHO Expert Committee on Food Additives (JECFA) and approved by FDA as a food additive and as UV protector. Substituted benzophenones such as oxybenzone (benzophenone-3) and dioxybenzone are used in sunscreens in cosmetics and as a sunscreen ingredients in some topical drugs in combination with skin lighteners for gradual fading of dark (brownish) areas in the skin such as freckles, age and liver spots or treatment of melanosis. Benzophenone derivatives can be used as a photo initiators. Benzophenone used in practical synthesis of some drugs.
