Description
1-Naphthol is a high-purity aromatic alcohol offered at min. 99 %, p.a., with CAS number 90-15-3 and empirical formula C₁₀H₈O. Key physical data include a molar mass of 144,17 g/mol, density of 1,28 g/cm³, flash point of 125 °C, and boiling range of 278 to 280 °C, supporting controlled handling and formulation. The compound is used as a staining reagent and analytical intermediate in environmental analysis and related laboratory applications where a defined naphthol building block is required. This grade comes from manufacturer Carl ROTH and is positioned for analytical and environmental laboratory use. The combination of high minimum purity and documented physicochemical properties aids reproducible solution preparation. Observe standard precautions for organic solids (UN 2811 classification applies) and consult the safety documentation prior to use.

Questions about 1-Naphthol, min. 99 %, p.a., 50 g, glass
What is this article?
1-Naphthol, min. 99 %, p.a., 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?
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.
