Description
Glycerol ROTIPURAN®, approx. 86 %, p.a. is a high-grade analytical solvent and reagent with CAS number 56-81-5 and empirical formula C₃H₈O₃. It has a molar mass of 92,09 g/mol, a density of 1,22 to 1,23 g/cm³, a flash point of 180 °C and a boiling point of 290 °C, supporting reliable performance in quantitative and qualitative laboratory work. a.), sample preparation, cryoprotection protocols and general wet-chemistry applications where a defined polyol medium is required. The material is offered from manufacturer Carl ROTH under the ROTIPURAN® line for analytical use. Its physical profile and approx. 86 % concentration make it a practical choice for research, quality-control and teaching laboratories that need consistent glycerol for dilutions, density work and solvent systems. The plastic bottle format supports routine handling and storage on the bench or in chemical stores.
This article belongs on Analytical grade solvents (p.a.), in Solvents.

Questions about Glycerol , ROTIPURAN®, approx. 86 %, p.a., 100 ml, glass
What is this article?
Glycerol , ROTIPURAN®, approx. 86 %, p.a., 100 ml, 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?
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.
