The formulation of a biochemical compound is listed under the Technical Information on the product’s webpage and the product’s insert. Biochemical compounds are supplied as either a solid, neat oil, or solution and are sold by weight. A solid can appear crystalline or as a fine powder and vary in color. A neat oil is a pure compound that did not crystallize during synthesis or purification. The compound itself is a liquid (i.e. an oil), and no solvent has been added to the supplied product. It is supplied by weight, and a volume is not recorded. A solution is a homogeneous mixture of a compound dissolved in a solvent. The supplied weight of the compound and volume of the solvent are printed on the label of the vial. The density is not determined for our products.
