Description
Anthraquinone, ROTI®Calipure is a melting point standard for the interval 283–286 °C, used to support calibration and performance checks in melting point determination. It is specified with CAS number 84-65-1, empirical formula C₁₄H₈O₂ and EG nr. 201-549-0, and a molar mass of 208,22 g/mol. Additional physical properties include a density of 1,261 g/cm³, flash point of 250 °C and boiling point of 380 °C, giving a coherent data set alongside the melting range. The product is supplied as 1 g in glass for convenient handling of reference material. This ROTI®Calipure anthraquinone from manufacturer Carl ROTH belongs to the melting point standards portfolio for determination of physical properties in analytical and quality-control laboratories. Typical applications include verifying instrument readings at elevated melting temperatures and establishing reference points in method documentation. The small glass pack supports precise use of limited standard quantities. Select Anthraquinone ROTI®Calipure when a high-temperature melting point standard around 283–286 °C with clear chemical identity is required.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Anthraquinone, ROTI®Calipure, Melting point standard 283-286 °C, 1 g, glass
What is this article?
Anthraquinone, ROTI®Calipure, Melting point standard 283-286 °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?
