Description
Zeaxanthin is a xanthophyll carotenoid reference standard provided as ROTICHROM® HPLC grade for high-performance liquid chromatography. With CAS number 144-68-3 and empirical formula C₄₀H₅₆O₂, the compound has a molar mass of 568,85 g/mol and is used for identification and quantification of oxygenated carotenoids in analytical chemistry. Packed as 5 mg in glass, it supports calibration, method development, and quality-control tasks in laboratories working with phytochemical and natural-product samples. This zeaxanthin standard from manufacturer Carl ROTH is suited to HPLC workflows that require a well-defined reference for peak confirmation and comparative analysis of plant extracts and related matrices. Applications include food, nutrition, and botanical research where xanthophyll profiles must be assessed with consistent reference material. The ROTICHROM® HPLC designation indicates suitability for liquid-chromatographic standards use. The small glass pack format is practical for establishing and maintaining reference stocks for routine analytical sequences.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Zeaxanthin, ROTICHROM® HPLC, 5 mg, glass
What is this article?
Zeaxanthin, ROTICHROM® HPLC, 5 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
