Beschrijving

Benzoic acid is een aromatisch carbonzuur, aangeboden met een minimale zuiverheid van 99.5 % in p.a.- en ACS-kwaliteit. Het wordt gekenmerkt door CAS-nummer 65-85-0, empirische formule C₇H₆O₂ en een molaire massa van 122.12 g/mol, met een dichtheid van 1.321 g/cm³, een kookpunt van 249 °C en een vlampunt van 121 °C. Gekoppeld aan EG-nummer 200-618-2 wordt het gebruikt in titratiestandaarden, ondersteunend werk voor organische synthese en laboratoriumprocedures die ACS-conforme benzoic acid vereisen. De combinatie van hoog gehalte, gedocumenteerde thermische gegevens en stabiele fysische eigenschappen ondersteunt reproduceerbare resultaten in onderzoek, kwaliteitscontrole en routinematige analytische workflows.

Dit artikel maakt deel uit van Oplosmiddelen van analytische kwaliteit (p.a.), in Oplosmiddelen.

Questions about Benzoic acid, min. 99.5 %, p.a., ACS, 100 g, kunststof

What is this article?

Benzoic acid, min. 99.5 %, p.a., ACS, 100 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Oplosmiddelen van analytische kwaliteit (p.a.), inside Oplosmiddelen, 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.
