Description
Cholecalciferol is a high-purity vitamin D₃ reference material offered in the ROTI®Star grade at min. 99 % purity for analytical and research use. It is identified by CAS number 67-97-0, EG number 200-673-2 and the empirical formula C₂₇H₄₄O, with a molar mass of 384,64 g/mol. This 100 mg pack is supplied in an HDPE container, supporting convenient handling of small quantities in the laboratory. Cholecalciferol from manufacturer Carl ROTH is suited to calibration, method development and other applications that require a well-defined sterol standard. The material belongs to the broader chemicals portfolio used across analytical chemistry and life-science workflows. Clear identity data (CAS, EG number and formula) facilitate documentation and traceability in regulated or research environments. Laboratories working with fat-soluble vitamins, nutritional analysis or related biochemical studies can integrate this ROTI®Star cholecalciferol into their reference-material inventory with confidence in the stated minimum purity and pack format.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about Cholecalciferol, ROTI®Star, min. 99 %, 100 mg
What is this article?
Cholecalciferol, ROTI®Star, min. 99 %, 100 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?
