Description
Acetic acid ethyl ester, ROTIPURAN® is a high-purity solvent grade with minimum 99,5 % assay, specified p.a., ACS and ISO for analytical laboratory use. Identified by CAS number 141-78-6 and empirical formula C₄H₈O₂, it has a molar mass of 88,11 g/mol, density 0,9003 g/cm³, flash point −4 °C and boiling point 77,1 °C (EG nr. 205-500-4). Supplied in a 1 l glass pack, this ethyl ester solvent is intended for solvents for analysis (p.a.) workflows, extractions, sample preparation and general chemical applications that require a defined purity profile. The ROTIPURAN® quality from manufacturer Carl ROTH addresses laboratories needing ACS- and ISO-aligned ethyl acetate for reproducible analytical methods. Physical data support method development where volatility, density and boiling behaviour matter. Handle as a flammable organic solvent in accordance with laboratory safety practice and the accompanying documentation.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Acetic acid ethyl ester, ROTIPURAN®, min. 99,5 %, p.a., ACS, ISO
What is this article?
Acetic acid ethyl ester, ROTIPURAN®, min. 99,5 %, p.a., ACS, ISO is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants de qualité analytique (p.a.), inside Solvants, in Produits chimiques.
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 Solvants. The sub-category is Solvants de qualité analytique (p.a.). The catalogue is Produits chimiques.
