Description
Acetanilide, ROTI®Calipure is a melting point standard covering the range 113–116 °C, supplied as 1 g in glass for calibration of melting-point apparatus. The compound has the empirical formula C₈H₉NO, molar mass 135,17 g/mol, density 1,121 g/cm³, flash point 161 °C and boiling point 304 °C, with CAS number 103-84-4 and EG nr. 203-150-7. These reference data support accurate instrument verification in laboratories that determine physical properties of organic solids. Offered from manufacturer Carl ROTH under the ROTI®Calipure line, the material is intended for melting-point determination workflows rather than synthetic use. Defined melting behaviour in the 113–116 °C window allows operators to check thermometer accuracy and apparatus performance against a known organic standard. The 1 g glass pack provides a practical quantity for repeated calibration runs while protecting the solid from moisture and contamination. Density of 1,121 g/cm³ and thermal data including flash point 161 °C and boiling point 304 °C complete the physicochemical profile needed for safe laboratory handling. Acetanilide ROTI®Calipure integrates readily into quality systems that require documented melting-point standards for routine equipment qualification.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Acetanilide, ROTI®Calipure, Melting point standard 113-116 °C, 1 g, glass
What is this article?
Acetanilide, ROTI®Calipure, Melting point standard 113-116 °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?
