Description
Acetic acid ethyl ester (CAS 141-78-6) is a dry laboratory solvent supplied as ROTIDRY® plus with a minimum purity of 99,8 % and water content limited to max. 50 ppm. Its empirical formula is C₄H₈O₂ and the molar mass is 88,11 g/mol. The liquid shows a density of 0,9003 g/cm³, a boiling point of 77,1 °C and a flash point of −4 °C. This grade is provided with molecular sieve to help preserve the low-water specification during storage. Offered in a 1 l pack from manufacturer Carl ROTH, it is intended for moisture-sensitive synthesis, chromatography and general laboratory work that benefits from a tightly controlled residual water level. The high assay and molecular-sieve packaging support consistent performance in anhydrous protocols. Physical constants and identity references, including EG nr. 205-500-4, facilitate straightforward specification checks in research and quality-controlled environments.
This article belongs on Dry & deuterated solvents (NMR, synthesis), in Solvents.

Questions about Acetic acid ethyl ester, ROTIDRY®, plus min. 99,8 % (max. 50 ppm H2O), 1 l
What is this article?
Acetic acid ethyl ester, ROTIDRY®, plus min. 99,8 % (max. 50 ppm H2O), 1 l is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dry & deuterated solvents (NMR, synthesis), inside Solvents, in Lab chemicals.
A dry solvent has had water removed to a stated level, for a reaction that water would stop. A deuterated solvent replaces hydrogen with deuterium so an NMR spectrum is not drowned by the solvent signal. The isotopic enrichment and the water content are the two specifications. Caps and septa matter, because either product picks up moisture from the air.
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 Dry & deuterated solvents (NMR, synthesis). The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, 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.
