Description
m-Toluic acid, ROTI®Calipure is a melting point standard covering the range 107–113 °C for calibration and verification work in physical-property determination. The compound has the empirical formula C₈H₈O₂, CAS number 99-04-7 and EG nr. 202-723-9, with a molar mass of 136,15 g/mol. Manufacturer data list a density of 1,24 g/cm³, a flash point of 159 °C and a boiling point of 264 °C, supporting clear identification in analytical documentation. Supplied as a 1 g pack in glass, this ROTI®Calipure grade material is intended for melting-point apparatus checks and related laboratory calibration routines. The reference substance from manufacturer Carl ROTH suits quality-control and teaching laboratories that rely on defined melting intervals for instrument qualification. Its well-characterised thermal profile helps laboratories establish reproducible melting-point measurements under controlled conditions. Use the standard wherever a documented m-toluic acid melting-point reference is required for routine verification of melting-point equipment.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about m-Toluic acid, ROTI®Calipure, Melting point standard 107-113 °C, 1 g, glass
What is this article?
m-Toluic acid, ROTI®Calipure, Melting point standard 107-113 °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?
