Description
Salicylic acid, ROTI®Calipure is a melting point standard specified for the interval 158–160 °C and intended for calibration and verification of melting point apparatus in analytical laboratories. The compound is identified by CAS number 69-72-7 and EG number 200-712-3, with the empirical formula C₇H₆O₃, a molar mass of 138,12 g/mol and a density of 1,44 g/cm³. Further physical data include a boiling point of 256 °C and a flash point of 157 °C, supporting informed handling under controlled laboratory conditions. Supplied as 1 g in glass, the pack size suits reference use, method validation and routine instrument checks while limiting unnecessary material consumption. Melting point standards of this type are applied in pharmaceutical, chemical and academic workflows where a defined thermal interval is required for reproducible results. This ROTI®Calipure grade from manufacturer Carl ROTH integrates into established physical-property determination protocols and quality-control sequences. Clear indication of the melting range allows straightforward selection alongside related calibration substances for consistent thermal measurement practice.

Questions about Salicylic acid, ROTI®Calipure, Melting point standard 158-160 °C, 1 g, glass
What is this article?
Salicylic acid, ROTI®Calipure, Melting point standard 158-160 °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?
