Description
Benzophenone, ROTI®Calipure is a melting point standard specified for 47–49 °C, supplied for calibration and verification work in melting point determination. The compound has CAS number 119-61-9, empirical formula C₁₃H₁₀O, molar mass 182,22 g/mol and EG nr. 204-337-6. Physical data include density 1,1 g/cm³, flash point 150 °C and boiling point 304 to 306 °C. Packaged as 1 g in glass, it is intended for laboratories performing determination of physical properties and routine instrument checks. This ROTI®Calipure grade material is offered by manufacturer Carl ROTH within the melting point standards range. Use it where a defined melting interval is required to support reproducible calibration of melting point apparatus. The compact 1 g glass pack is convenient for controlled laboratory dispensing and reference use alongside other physical-property standards in analytical and quality-control settings.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Benzophenone, ROTI®Calipure, Melting point standard 47-49 °C, 1 g, glass
What is this article?
Benzophenone, ROTI®Calipure, Melting point standard 47-49 °C, 1 g, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Spectroscopy & physical property standards, inside Analytical standards & reference materials, in Lab chemicals.
These standards check a physical or optical measurement: a refractive-index liquid, a wavelength standard, a viscosity oil, a melting-point substance. The stated value and its uncertainty are the product. They are not general reagents.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
Which category should I open next?
The category is Analytical standards & reference materials. The sub-category is Spectroscopy & physical property standards. The catalogue is Lab chemicals.
Shelves beside this one are ICP, AAS & ion standards, Chromatography standards (GC, HPLC, pesticides), Reference substances & reagents (other), Volumetric standard solutions (titration), Reagents for analysis (Ph. Eur., ASTM, DIN) and Indicators & indicator solutions.
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.
