Description
2-Thiouracil is a sulfur-containing pyrimidine derivative supplied at min. 98 % purity for biochemistry. It is identified by CAS number 141-90-2 and EG nr. 205-508-8, with empirical formula C₄H₄N₂OS and a molar mass of 128,15 g/mol. This compound is employed in biochemical and medicinal-chemistry research as a nucleobase analogue, enzyme-related probe and intermediate for modified pyrimidine structures. Its thiocarbonyl functionality enables studies of base pairing, metabolic pathways and structure–activity relationships in nucleic-acid chemistry. The product is Available from manufacturer Carl ROTH in a biochemistry-oriented grade, it supports work where consistent identity and assay are essential. Researchers select 2-thiouracil for controlled experiments involving thiolated bases, antimetabolite models and related heterocyclic scaffolds. The defined molar mass and formula facilitate accurate preparation of solutions and stoichiometric calculations in both analytical and preparative settings.

Questions about 2-Thiouracil, min. 98 %, for biochemistry, 50 g, plastic
What is this article?
2-Thiouracil, min. 98 %, for biochemistry, 50 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Coenzymes, nucleotides & vitamins, inside Biochemicals & reagents, in Microbiology lab supplies.
Coenzymes, nucleotides and vitamins are the small molecules enzymes and cells consume: NAD, ATP, a vitamin cofactor. Purity, salt form and hydration are the specification, and many are unstable in solution or in the light. The lot is stored as the label says, often cold.
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.
