Description
Melatonin is a biochemical-grade reagent supplied at a minimum purity of 97 % for biochemistry applications. It is identified by CAS number 73-31-4 and EG number 200-797-7, with the empirical formula C₁₃H₁₆N₂O₂ and a molar mass of 232,28 g/mol. This material is offered as a 250 mg pack in glass, providing a convenient small quantity for method development, reference work, and routine biochemical experiments. Melatonin from manufacturer Carl ROTH is positioned for laboratory use where a defined organic indoleamine standard or intermediate is required in research and analytical settings. The stated purity and clear identity data support formulation of working solutions and comparison against established protocols. Typical contexts include biochemistry workflows, signalling and chronobiology studies, and general organic reagent handling under controlled laboratory conditions. The compact glass presentation aids organised storage and accurate weighing of small amounts. Users should consult the accompanying safety documentation before handling and apply standard laboratory practice for organic solids used in biochemical research.

Questions about Melatonin, min. 97 %, for biochemistry, 250 mg, glass
What is this article?
Melatonin, min. 97 %, for biochemistry, 250 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biochemicals (other), inside Biochemicals & reagents, in Microbiology lab supplies.
These are the biochemical reagents that are not an amino acid, a sugar, a lipid, an enzyme or an antibiotic. Identity and purity still decide the bottle. If the compound is light-sensitive or hygroscopic, the handling on the label is part of the specification.
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.
