Description
Sodium azide is an inorganic azide salt supplied at a minimum purity of 99 % in p.a. analytical grade. It is identified by CAS number 26628-22-8 and the empirical formula NaN₃, with a molar mass of 65,01 g/mol and a density of 1,846 g/cm³. The product is This high-assay grade is applied in water analysis and biological oxygen demand (BOD) testing, as well as in biochemical and sample-preservation workflows where azide is used as a reagent. Laboratories select p.a. sodium azide when low impurity levels and reliable identity data are essential for quantitative methods. Available from manufacturer Carl ROTH, the material supports environmental laboratories, research groups, and quality-control units working with aqueous systems and specialized inorganic preparations. Clear specification of molar mass, density, and purity assists method validation and day-to-day analytical consistency under controlled laboratory conditions.

Questions about Sodium azide, min. 99 %, p.a., 50 g, glass
What is this article?
Sodium azide, min. 99 %, p.a., 50 g, glass 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?
