Description
Nitric acid ROTIPURAN® is a high-grade mineral acid offered at min. 65 % with p.a. and ISO quality designations for analytical laboratory use. It is identified by CAS number 7697-37-2 and EG nr. 231-714-2, with the empirical formula HNO₃, a molar mass of 63,01 g/mol, a density range of 1,39 to 1,41 g/cm³ and a boiling range of 120 to 121 °C. The product is classified under UN number 2031 and is intended for demanding analytical workflows such as sample digestion, environmental analysis, reagent preparation and general wet-chemical procedures that require a defined concentrated nitric acid. Manufactured by Carl ROTH under the ROTIPURAN® line, this acid combines stated purity, ISO/p.a. grading and transparent physicochemical data for laboratories that specify min. 65 % nitric acid for analysis. Its clear specification profile supports reproducible results in quality-control and research environments.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Nitric acid , ROTIPURAN®, min. 65 %, p.a., ISO, 1 l, glass
What is this article?
Nitric acid , ROTIPURAN®, min. 65 %, p.a., ISO, 1 l, 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?
