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

The nature of products in the diazotization of 1-amino-2-acetylenyl-9,10-anthraquinones strongly depends on the nature of substituents at both the alkyne and at the anthraquinone core. Donor substitution (NHAr, OH) at the fourth position stabilizes the diazonium salt at C1, decelerating
