Description
Diphenylmethanol is an organic synthesis reagent supplied at a minimum purity of 99 % for laboratory preparative work. It has the empirical formula C₁₃H₁₂O, CAS number 91-01-0, EG nr. 202-033-8 and a molar mass of 184,24 g/mol, with a boiling point of 297 to 298 °C. Available from manufacturer Carl ROTH, this grade supports method development, intermediate preparation and related synthetic routes in research and teaching laboratories. Clear identity data—including CAS 91-01-0 and formula C₁₃H₁₂O—facilitate specification checks in purchasing and quality documentation. The min. 99 % purity designation for synthesis use aligns with common requirements for controlled organic transformations. The compact is practical for laboratories that need defined quantities without bulk storage. Diphenylmethanol remains a standard entry in A-to-Z chemical catalogues for synthetic chemistry workflows.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about Diphenylmethanol, min. 99 %, for synthesis, 10 g, glass
What is this article?
Diphenylmethanol, min. 99 %, for synthesis, 10 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.
