Description
Hydrogen peroxide ROTIPURAN® Ultra 31 % is an aqueous oxidising reagent with empirical formula H₂O₂, CAS number 7722-84-1 and molar mass 34,02 g/mol. It shows a density of 1,11 g/cm³ and a boiling point of 107 °C, supporting use in digestion, oxidation and sample-preparation steps. Delivered as 500 ml in a plastic (FEP) bottle, this grade suits environmental analysis and reagents and reference material workflows linked to AAS, ICP and IC standards. The EG number is 231-765-0. Defined concentration and physical data help laboratories maintain consistent oxidant strength for wet-chemical procedures and instrumental sample work-up. This hydrogen peroxide from manufacturer Carl ROTH fits inorganic reagent sets where controlled peroxide addition is required. Molar mass, density and boiling point information assist documentation, method validation and safe bench practice in analytical and environmental laboratories that rely on ROTIPURAN® Ultra quality materials.

Questions about Hydrogen peroxide , ROTIPURAN® Ultra 31 %, 500 ml, plastic (FEP)
What is this article?
Hydrogen peroxide , ROTIPURAN® Ultra 31 %, 500 ml, plastic (FEP) 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?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
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.
