Description
D(+)-Biotin is a biochemistry-grade vitamin reagent of Ph.Eur. quality with a minimum assay of 98,5 %. It is identified by CAS number 58-85-5 and EG number 200-399-3, with the empirical formula C₁₀H₁₆N₂O₃S, a molar mass of 244,31 g/mol and a density of 1,41 g/cm³. This D(+)-biotin grade supports enzyme cofactor studies, metabolic pathway work and other biochemical applications that require a defined vitamin standard of pharmacopoeia quality. The material is Its documented identity and purity profile suit calibration tasks, nutritional biochemistry and method development in regulated settings. Laboratories working with vitamins (Ph.Eur., USP, BP) and chemicals in pharmacopoeia quality can integrate this grade into routine assays and research protocols where consistent composition matters. The glass pack supports clean handling of the solid during day-to-day laboratory workflows.

Questions about D(+)-Biotin, min. 98,5 %, Ph.Eur., for biochemistry, 500 mg, glass
What is this article?
D(+)-Biotin, min. 98,5 %, Ph.Eur., 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.
