Abstract: An insert for an EPR probehead is disclosed. The insert comprises a directional coupler and an amplifier. The directional coupler receives microwave power from a source at a first port and transfers a portion of the received microwave power to a second port for transmission to a sample space. The directional coupler is also arranged to receive a microwave signal from the sample space at the second port and to pass the majority of the received microwave signal to a third port. The amplifier has an input and an output; the input is arranged to receive the microwave signal from the third port of the directional coupler and to produce an amplified version of the received microwave signal at the output for transmission to a detector.

Abstract: A new azido compound, 5-amino-6-chloro-2,4-diazido-pyrimidine, and a process for synthesizing. The synthesis may include reacting 5-amino-2,4,6-trichloropyrimidine and sodium azide. There is an excess molar amount of sodium azide for each chloro fractional molar amount on the 5-amino-2,4,6-trichloropyrimidine. The synthesis is a two phase reaction that is a dispersion. The 5-amino-2,4,6-trichloropyrimidine dissolved in acetone is a liquid phase, and the sodium azide is insoluble in acetone and is a solid phase, that is present in excess of chemical equivalents. The reaction product is soluble in acetone, and the reaction by-product, sodium chloride is also insoluble in acetone, and the crude yield is about 92%. Unreacted sodium azide and formed sodium chloride are removed by filtration.
