Description
Biotin is a high-purity laboratory reagent offered as ROTI®Star grade with a minimum assay of 99 %. It is identified by CAS number 58-85-5, EG number 200-399-3 and the empirical formula C₁₀H₁₆N₂O₃S, with a molar mass of 244,31 g/mol and a density of 1,41 g/cm³. This vitamin H compound is widely applied in biochemistry, molecular biology and diagnostic development, where it functions as an essential cofactor for carboxylase enzymes and as a robust affinity handle for biotin–streptavidin detection systems. The material supports protein and nucleic-acid labeling, cell-culture media supplementation and assay calibration work that demand a defined purity level. Packed as 250 mg in an HDPE container, the presentation is practical for method development and routine laboratory use. Sourced from manufacturer Carl ROTH, ROTI®Star biotin provides consistent quality for research, quality-control and analytical workflows. Its well-documented physicochemical profile helps laboratories maintain reproducible conditions across biotinylation protocols, ELISA formats and related affinity techniques without introducing unnecessary variability into experimental design.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Biotin, ROTI®Star, min. 99 %, 250 mg
What is this article?
Biotin, ROTI®Star, min. 99 %, 250 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
