Description
Benzoic acid, ROTI®Calipure is a melting point standard specified for the range 121–123 °C and used to calibrate and verify laboratory melting-point apparatus. The material carries CAS number 65-85-0, EG number 200-618-2 and the empirical formula C₇H₆O₂, with a molar mass of 122,12 g/mol and a density of 1,321 g/cm³. Thermal characteristics include a flash point of 121 °C and a boiling point of 249 °C, supporting reproducible physical-property work. Supplied as 1 g in glass, the pack is practical for analytical benches and quality-control laboratories that maintain reference standards. Data from manufacturer Carl ROTH reflect established values for benzoic acid, allowing confident instrument checks across the stated melting interval. Typical applications include determination of physical properties and routine melting-point determination where a defined standard is required. This ROTI®Calipure grade helps laboratories confirm apparatus performance with clearly documented physicochemical parameters suitable for everyday calibration and method validation tasks in research and industrial settings. The glass presentation supports straightforward handling when preparing samples for melting-point runs.

Questions about Benzoic acid, ROTI®Calipure, Melting point standard 121-123 °C, 1 g, glass
What is this article?
Benzoic acid, ROTI®Calipure, Melting point standard 121-123 °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?
