Description
Ammonia-D₃ solution 25 % in D₂O is a deuterated ammonia reagent supplied at 99 Atom%D for nuclear magnetic resonance work and related spectroscopic applications. It carries CAS number 12168-30-8 and is described by the empirical composition ND₃ + D₂O, with a molar mass of 40,08 g/mol and a density of 1,056 g/cm³. The 25 % solution in heavy water provides a convenient deuterium-enriched ammonia source for labelling studies, solvent systems and NMR reference or reaction media where high isotopic enrichment is required. Offered in a 10 ml glass pack, the material is suited to analytical and research laboratories that prepare deuterated samples under controlled conditions. This grade is available from manufacturer Carl ROTH within the compounds-for-NMR range and supports spectroscopy workflows that depend on defined Atom%D content, stable physical data and a compact laboratory pack size for precise handling and dosing.
This article is part of Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about Ammonia-D3 solution 25 % in D, 99 Atom%D, 10 ml, glass
What is this article?
Ammonia-D3 solution 25 % in D
A dry solvent has had water removed to a stated level, for a reaction that water would stop. A deuterated solvent replaces hydrogen with deuterium so an NMR spectrum is not drowned by the solvent signal. The isotopic enrichment and the water content are the two specifications. Caps and septa matter, because either product picks up moisture from the air.
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.
