Description
Theobromine is a methylxanthine reference material offered in ROTICHROM® HPLC quality for chromatographic and analytical laboratory use. It is identified by CAS number 83-67-0, EG number 201-494-2, and the empirical formula C₇H₈N₄O₂, with a molar mass of 180,16 g/mol and a density of 1,522 g/cm³. The product is packed as 20 mg in glass, providing a practical quantity for method development, calibration, and qualitative or quantitative HPLC work. Available from manufacturer Carl ROTH, this theobromine grade supports analytical chemistry workflows that require a well-defined xanthine standard. Its documented physicochemical data facilitate preparation of stock solutions and comparison against chromatographic retention or spectral libraries. Typical use includes research and quality-control environments handling plant alkaloids, food-related methylxanthines, or related synthetic studies where a dedicated HPLC-oriented reference is preferred.

Questions about Theobromine, ROTICHROM® HPLC, 20 mg, glass
What is this article?
Theobromine, ROTICHROM® HPLC, 20 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Lab chemicals.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is HPLC & LC-MS grade solvents. The catalogue is Lab chemicals.
