Description
Vanillin ROTI®Calipure is a melting point standard defined for the 81–83 °C interval, used to calibrate and check melting point instruments in the laboratory. The compound carries CAS number 121-33-5 and empirical formula C₈H₈O₃, with a molar mass of 152,15 g/mol and a density of 1,06 g/cm³. Reported thermal data include a flash point of 159,8 to 160,8 °C and a boiling point of 285 °C, together with EG nr. 204-465-2. This 1 g glass unit from manufacturer Carl ROTH belongs to the ROTI®Calipure line of reference materials for determination of physical properties. It is appropriate for analytical and quality-control settings that maintain graded melting point standards across successive temperature ranges. The small glass pack supports orderly storage of calibration solids and repeated verification of apparatus performance during routine melting point determination work in research, teaching and industrial laboratories.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Vanillin ROTI®Calipure, Melting point standard 81-83 °C, 1 g, glass
What is this article?
Vanillin ROTI®Calipure, Melting point standard 81-83 °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?
