Description
Vitamin B₁₂ is a biochemical reagent offered at a minimum purity of 96 % for biochemistry applications. Bearing CAS number 68-19-9 and the empirical formula C₆₃H₈₈CoN₁₄O₁₄P, it has a molar mass of 1355,4 g/mol and serves laboratories that require a defined cobalamin material for analytical and experimental work. The product is Available from manufacturer Carl ROTH, this grade is intended for biochemical use where consistent identity and a stated minimum assay support reproducible results. Typical contexts include nutritional biochemistry, metabolic studies, and method development involving vitamin B₁₂-related pathways. The clearly specified molecular formula and molar mass facilitate accurate weighing and molar calculations at the bench. Glass containment helps protect the solid during handling and transfer in controlled laboratory environments. Researchers in academic, clinical-research, and industrial settings can incorporate this material into protocols that call for a high-purity vitamin B₁₂ reagent with documented composition and assay.

Questions about Vitamin B12, min. 96 %, for biochemistry, 500 mg, glass
What is this article?
Vitamin B12, min. 96 %, for biochemistry, 500 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Coenzymes, nucleotides & vitamins, inside Biochemicals & reagents, in Life Science & Microbiology.
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.
