Description
8-Hydroxyquinoline is an analytical complexing agent supplied in p.a. and ACS quality, with CAS number 148-24-3 and empirical formula C₉H₇NO. The compound has a molar mass of 145,16 g/mol, a density of 1,034 g/cm³ and a boiling point of 267 °C. It is Identity data from manufacturer Carl ROTH also include EG number 205-711-1 and UN number 2811, which support inventory and transport classification. 8-Hydroxyquinoline is listed among complexing agents for complexometry, where laboratories specify p.a. or ACS reagents. The formula C₉H₇NO and the molar mass of 145,16 g/mol enable accurate weighing from when solutions or reagent mixtures are prepared. Density and boiling point provide additional physical constants for laboratory records. Users should refer to the safety data sheet for handling information associated with UN 2811. The pack size, grade and published constants describe this of 8-hydroxyquinoline, p.a., ACS. Molar mass, density and boiling point are the values stated for this p.a., ACS grade.

Questions about 8-Hydroxyquinoline, p.a., ACS, 50 g, glass
What is this article?
8-Hydroxyquinoline, p.a., ACS, 50 g, glass 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 Lab chemicals.
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 Lab chemicals.
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?
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.
