Description
Sulphanilamide, ROTI®Calipure is a melting point standard defined for the range 164–166 °C and intended for calibration and performance verification of melting point instruments. The substance carries CAS number 63-74-1 and EG number 200-563-4, with the empirical formula C₆H₈N₂O₂S, a molar mass of 172,21 g/mol and a density of 1,08 g/cm³. These identity and physical data support correct selection and documentation in analytical workflows. The product is packed as 1 g in glass, a convenient reference format for method validation, instrument qualification and routine thermal checks. Melting point standards of this class are widely used in pharmaceutical, chemical and academic laboratories where a tightly specified melting interval underpins reproducible results. Available from manufacturer Carl ROTH within the ROTI®Calipure series, the material fits established physical-property determination protocols. Clear labelling of the 164–166 °C interval simplifies pairing with complementary calibration substances and helps maintain consistent practice across melting point determination sequences.
This article is part of Spectroscopy & physical property standards, in Analytical standards & reference materials.

Questions about Sulphanilamide, ROTI®Calipure, Melting point standard 164-166 °C, 1 g, glass
What is this article?
Sulphanilamide, ROTI®Calipure, Melting point standard 164-166 °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.
