Description
Ammonia solution ROTIPURAN® Ultra 20 % est un réactif ammonia aqueux de formule empirique NH₃ + H₂O, numéro CAS 1336-21-6 et n° EG 215-647-6. La masse molaire est indiquée comme 17.03 + aq g/mol et la densité va de 0.92 à 0.94 g/cm³. Cette qualité définie à 20 %. ROTIPURAN® Ultra du fabricant Carl ROTH prend en charge les workflows qui nécessitent une ammonia solution contrôlée avec des données d'identité traçables. Des informations claires sur le CAS, l'EG et la densité facilitent la documentation des étalons, des étapes de digestion ou de complexation et le contrôle qualité de routine. Le format de flacon HDPE est pratique pour une utilisation sur paillasse lorsque de l'ammonia aqueux est requis comme base ou milieu complexant en chimie analytique.

Questions about Ammonia solution, ROTIPURAN® Ultra 20 %, 500 ml, HDPE
What is this article?
Ammonia solution, ROTIPURAN® Ultra 20 %, 500 ml, HDPE is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Solvants. The sub-category is Solvants de qualité analytique (p.a.). The catalogue is Produits chimiques.
Shelves beside this one are Solvants de qualité HPLC & LC-MS, Solvants secs & deutérés (NMR, synthèse), Solvants de qualité technique & synthèse and Solvants verts & alternatifs.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
