Description
Cholic acid is a bile acid of minimum 99 % purity supplied for laboratory use, with CAS number 81-25-4 and empirical formula C₂₄H₄₀O₅. The compound has a molar mass of 408,58 g/mol and a density of 1,13 g/cm³, supporting accurate weighing and formulation in life-science and microbiology workflows. As a nutrient media additive, cholic acid is employed in selective culture media and biochemical studies involving bile-salt tolerance, microbial physiology and related experimental systems. This grade is The material from manufacturer Carl ROTH is listed under EG number 201-337-8 and fits catalogues of defined organic acids used in microbiology and analytical biochemistry. Researchers preparing differential media, investigating detergent-like effects of bile acids or standardising reference solutions will find the stated purity and pack size practical. Store and handle according to laboratory good practice for organic solids. Intended for professional laboratory applications in nutrient media formulation and related biochemical work.

Questions about Cholic acid, min. 99 %, 25 g, plastic
What is this article?
Cholic acid, min. 99 %, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Lipids, steroids & fatty acids, inside Biochemicals & reagents, in Microbiology lab supplies.
A lipid, a steroid or a fatty acid is specified by chain length, saturation and purity. Esters and free acids are different compounds. Many are supplied in a small amount under inert gas because they oxidise. The physical form, oil or powder, follows from the structure.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
