Description
Phenacetin, ROTI®Calipure is a melting point standard specified for the interval 133–135 °C, used to calibrate and verify melting-point determination instruments. The substance carries CAS number 62-44-2 and EG number 200-533-0, with empirical formula C₁₀H₁₃NO₂, molar mass 179,22 g/mol and density 1,23 g/cm³. It is supplied as a 1 g quantity in a glass container, convenient for controlled dispensing of calibration aliquots in analytical laboratories. Melting-point standards of this type support method validation, instrument qualification and routine performance checks in pharmaceutical, chemical and materials testing environments. The ROTI®Calipure grade from manufacturer Carl ROTH provides a clearly defined reference material aligned with physical-property determination workflows. Documented molecular identity and melting range simplify entry into SOPs, calibration certificates and quality-system records. Compact glass packaging protects the solid during storage and handling on the laboratory bench. Laboratories performing melting-point analysis can integrate this standard alongside other reference substances covering adjacent temperature ranges for comprehensive instrument verification.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Phenacetin, ROTI®Calipure, Melting point standard 133-135 °C, 1 g, glass
What is this article?
Phenacetin, ROTI®Calipure, Melting point standard 133-135 °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?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
