Beschrijving
Ethyleenglycoldistearaat is een biochemische diester met een minimale zuiverheid van 85 %, geïdentificeerd door CAS-nummer 627-83-8 en de brutoformule C₃₈H₇₄O₄. Met een molaire massa van 594,99 g/mol is deze verbinding uitermate geschikt voor laboratoriumwerk waarvoor een gedefinieerde vetzuurglycolesther vereist is. Het gehalte van min. 85 % ondersteunt reproduceerbare werkprotocollen en vergelijkend onderzoek. Identiteit en samenstelling worden gestaafd door het vermelde CAS-registernummer en de molecuulformule, wat zorgt voor een duidelijke documentatie voor methodelogboeken. Het materiaal is verkrijgbaar bij de fabrikant Carl ROTH en past in standaard chemische en biochemische catalogi.
Dit artikel hoort bij Analytische oplosmiddelen (p.a.), in Oplosmiddelen.

Questions about Ethyleenglycoldistearaat, min. 85 %, 500 g
What is this article?
Ethyleenglycoldistearaat, min. 85 %, 500 g 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 Chemicaliën.
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 Chemicaliën.
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?
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.
