Description
Riboflavin is a high-purity biochemical reagent offered in the ROTI®Star grade at a minimum assay of 99 %. It has the empirical formula C₁₇H₂₀N₄O₆, a molar mass of 376,36 g/mol, CAS number 83-88-5 and EG number 201-507-1. The material is packed as 250 mg in an HDPE container, a convenient small unit for analytical standards, vitamin research, fluorescence work and other laboratory applications that require tightly specified riboflavin. Physical identity is anchored by the stated molecular weight and formula, supporting accurate weighing and solution preparation in micro-scale protocols. This ROTI®Star quality from manufacturer Carl ROTH is intended for users who need a clearly documented vitamin B₂ reference material rather than bulk technical grades. The compact 250 mg fill minimises waste when only milligram quantities are consumed per experiment. Use the CAS and EG identifiers for inventory control, regulatory documentation and method traceability. Handle and dissolve the solid according to good laboratory practice so that the declared minimum purity is preserved through to the working solution.
This article is part of Coenzymes, nucleotides & vitamins, in Biochemicals & reagents.

Questions about Riboflavin
What is this article?
Riboflavin 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.
