Beschrijving
Theobromine is een organische referentiestof van hoge zuiverheid, geleverd als ROTICHROM® CHR met een minimaal gehalte van 99 % en geschiktheid Reag. Ph. Eur. De empirische formule is C₇H₈N₄O₂, de molaire massa is 180.16 g/mol en de dichtheid is 1.522 g/cm³; de verbinding wordt geïdentificeerd aan de hand van CAS-nummer 83-67-0 en EG-nummer 201-494-2. Verkrijgbaar van fabrikant Carl ROTH, is de kwaliteit ROTICHROM® CHR bedoeld voor gecontroleerd reagensgebruik waarbij gedocumenteerde zuiverheid en afstemming op de farmacopee van belang zijn. Fysische constanten zoals molaire massa en dichtheid ondersteunen het afwegen, de bereiding van oplossingen en de methodedocumentatie.

Questions about Theobromine, ROTICHROM® CHR, 10 g, kunststof
What is this article?
Theobromine, ROTICHROM® CHR, 10 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organische bouwstenen & synthesereagentia, inside Organische chemicaliën & synthesereagentia, in Chemicaliën.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
