Beschrijving
Pyridine D₅ is a highly deuterated NMR solvent with 99,5 Atom%D enrichment, empirical formula C₅D₅N, and CAS number 7291-22-7. The compound has a molar mass of 84,13 g/mol and a density of 1,05 g/cm³, making it suitable for dissolution and locking in nuclear magnetic resonance spectroscopy. Boiling point is 114 °C and flash point is 20 °C, parameters that support controlled handling in analytical laboratories. Supplied in a 10 ml glass pack, this material is positioned for spectroscopy and spectrometry workflows where residual proton interference must be minimised. Pyridine D₅ is frequently selected for structure confirmation, reaction monitoring, and studies of polar or aromatic analytes that require a basic deuterated medium. Physical and identity data from manufacturer Carl ROTH match the needs of routine and advanced NMR applications. The glass presentation provides a practical volume for method setup, calibration checks, and day-to-day sample preparation in research and quality-control environments.

Questions about Pyridine D5
What is this article?
Pyridine D5 is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Reference substances & reagents (other), inside Analytical standards & reference materials, in Chemicaliën.
A reference substance has a stated identity and a stated content, used to check a method or to standardise a titration. It is a more tightly specified article than a reagent grade bottle of the same name. The lot's certificate is part of the product.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Reference substances & reagents (other). The catalogue is Chemicaliën.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN), Spectroscopy & physical property standards and Indicators & indicator solutions.
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.
