Description
Pyridine D₅ is a fully deuterated pyridine solvent specified at 99,8 Atom%D for nuclear magnetic resonance spectroscopy and related analytical tasks. With CAS number 7291-22-7 and empirical formula C₅D₅N, it presents a molar mass of 84,13 g/mol and a density of 1,05 g/cm³. The boiling point is 114 °C and the flash point is 20 °C, values that guide safe laboratory handling of this aromatic deuterated medium. It is appropriate for sample dissolution, structure elucidation support, and routine spectroscopic workflows that require a deuterated heterocyclic solvent. The product is offered by manufacturer Carl ROTH among its compounds for NMR. Pyridine D₅ is frequently chosen when analytes demand a polar aromatic medium and when spectral clarity depends on tightly controlled isotopic purity. The stated Atom%D level, compact glass presentation, and documented density and boiling data help laboratories maintain consistent performance in research, method development, and quality-control NMR environments.

Questions about Pyridine D5, 99,8 Atom%D, 7.5 ml, glass ampoule
What is this article?
Pyridine D5, 99,8 Atom%D, 7.5 ml, glass ampoule 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?
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.
