Description
Ammonia solution ROTIPURAN® Ultra 20 % is an aqueous ammonia reagent with empirical formula NH₃ + H₂O, CAS number 1336-21-6 and EG nr. 215-647-6. The molar mass is given as 17,03 + aq g/mol and the density ranges from 0,92 to 0,94 g/cm³. This defined 20 %. ROTIPURAN® Ultra grade from manufacturer Carl ROTH supports workflows that need a controlled ammonia solution with traceable identity data. Clear CAS, EG and density information aids documentation of standards, digestion or complexation steps, and routine quality control. The HDPE bottle format is practical for bench use where aqueous ammonia is required as a base or complexing medium in analytical chemistry.
This article is part of Analytical grade solvents (p.a.), in Solvents.

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 Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
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 Solvents. The sub-category is Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
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.
