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.


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.

Chromatographic study of natural products helps to determine their molecular composition and to identify their sources (biological, geographical, etc.). However, identifying anthraquinoids is still a challenge because this chemical family is composed of more than half a thousand molecules. In

Nonlinear optical properties of 1,4-Diamino-9,10-Anthraquinone dye in solution at different concentrations are investigated by utilizing single beam Z-scan technique using a low power continuous wave laser (λ=532 nm). The anthraquinone dye is found to exhibit self-defocusing and reverse saturable absorption
