General description

Melting point standard 283-286 °C, anthraquinone is an analytical standard, suitable for the day-to-day calibration of melting point apparatus to guarantee its accuracy, in accordance with local, national and international standards laboratories.
The mp value is recorded as an average of 6 to 12 measurements with a Büchi B-545 equipment that is calibrated against primary standards. Melting point is determined by Capillary method, as described in Ph. Eur. 2.2.14.

Application

Anthraquinone melting point standard 283-286 °C is an mp standard used for physicochemical characterization.
This product also features as a reference standard in thermal property investigations.

Features and Benefits

  • Melting point calibration standard traceable to primary standards (LGC, London)
  • Grade: Analytical Standard
  • Melting point validated in the thermodynamic mode of analysis
  • Standard deviation up to ± 0.3 °C
  • Available with certificates of analysis and safety data sheet
