Beschrijving
4-Hydroxybenzoëzuurpropylester is een ROTICHROM® HPLC-grade verbinding met de empirische formule C₁₀H₁₂O₃, CAS-nummer 94-13-3 en een molaire massa van 180,21 g/mol. De gerapporteerde dichtheid is 1,287 g/cm³, met een vlampunt van 180 °C en een kookpunt van 301 °C, wat een solide fysisch-chemische basis vormt voor laboratoriumidentificatie. Deze glazen verpakking van 1 g van fabrikant Carl ROTH is bedoeld voor HPLC-gerelateerde toepassingen die een gedefinieerde propylester van 4-hydroxybenzoëzuur vereisen. EG-nummer 202-307-7 ondersteunt het volgen van de stof in documentatiesystemen. Analytische en wetenschappelijke laboratoria kunnen het materiaal gebruiken bij chromatografisch werk, referentievergelijkingen en methodeontwikkeling waarbij deze ester betrokken is. De compacte glazen presentatie is geschikt voor nauwkeurige hantering en kleinschalige voorraad in kwaliteitscontrole en chemische analyse.

Questions about 4-Hydroxybenzoëzuurpropylester, ROTICHROM® HPLC, 1 g, glas
What is this article?
4-Hydroxybenzoëzuurpropylester, ROTICHROM® HPLC, 1 g, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in HPLC & LC-MS grade solvents, inside Solvents, in Chemicaliën.
HPLC grade limits the absorbance and the residue that would appear as peaks or baseline drift. LC-MS grade goes further on metal ions and on particles that would suppress a mass spectrum. A solvent that is only analytical grade is a false economy on an LC-MS system.
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 HPLC & LC-MS grade solvents. The catalogue is Chemicaliën.
Shelves beside this one are Analytical grade solvents (p.a.), 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.
