oxandrolone Purified 99%

1.Oxandrolone (brand names Oxandrin, Anavar, Lonavar, others), is a synthetic, orally active anabolic-androgenic steroid (AAS) that first become available as a prescription drug in the United States in 1964. It is a 17α-methylated derivative of dihydrotestosterone (DHT) that has an oxygen atom in place of the carbon at the 2 position.

2.Oxandrolone is well-established as a safe treatment for patients recovering from severe burns.Medical research has also established oxandrolone's efficacy in aiding the development of girls with Turner syndrome. Although oxandrolone has long been used to accelerate growth in children with idiopathic short stature, it is unlikely to increase adult height and in some cases may even decrease it. Oxandrolone has therefore largely been replaced by growth hormone for this use.

tridecanal LAB GRADE 98%

Also known as 1-tridecanal or tridecanaldehyde, belongs to the class of organic compounds known as fatty aldehydes. These are long chain aldehydes with a chain of at least 12 carbon atoms. Thus, is considered to be a fatty aldehyde lipid molecule. exists as a liquid and is considered to be practically insoluble (in water) and relatively neutral. has been detected in multiple biofluids, such as feces, saliva, and urine. Within the cell, is primarily located in the membrane (predicted from logP) and cytoplasm. is a sweet, aldehydic, and citrus tasting compound that can be found in a number of food items such as lemon, fats and oils, corn, and citrus. This makes a potential biomarker for the consumption of these food products.

tridecanol LAB GRADE 98%

1-Tridecanol is a chemical compound from the group of alcohols (specifically, the fatty alcohols ). It is in the form of a colorless, flammable solid. 1-Tridecanol usually occurs as a mixture of different isomeric to compounds such as 2-tridecanol, 3-tridecanol, 4-tridecanol, 5-tridecanol, 6-tridecanol and isotridecanol.

1,3-oxazole LAB GRADE 98%

Oxazole is the parent compound for a vast class of heterocyclic aromatic organic compounds. These are azoles with an oxygen and a nitrogen separated by one carbon. Oxazoles are aromatic compounds but less so than the thiazoles. Oxazole is a weak base; its conjugate acid has a pKa of 0.8, compared to 7 for imidazole.

1-eicosanol LAB GRADE 98%

A waxy substance used as an emollient in cosmetics. It is a straight-chain fatty alcohol typically obtained via the hydrogenation of arachidic acid or arachidonic acid, both of which are present in peanut oil. Its name is derived from that of the peanut plant.
