Device and methods for use in a biosensor comprising a multisite array of test sites, the device and methods being useful for modulating the binding interactions between a (biomolecular) probe or detection agent and an analyte of interest by modulating the pH or ionic gradient near the electrodes in such biosensor. An electrochemically active agent that is suitable for use in biological buffers for changing the pH of the biological buffers. Method for changing the pH of biological buffers using the electrochemically active agents. The methods of modulating the binding interactions provided in a biosensor, analytic methods for more accurately controlling and measuring the pH or ionic gradient near the electrodes in such biosensor, and analytic methods for more accurately measuring an analyte of interest in a biological sample.

There is provided a compound of formula (I)

##STR00001##

which is a homoallylic ether of a phenolic fragrant compound HX and which is able to release said phenolic fragrant compound HX.

Methods are provided for the synthesis of cannabinoids, including cannabidiol (CBD), cannabinol (CBN), cannabichromene (CBC), cannabidiolic acid (CBDA), cannabigerol (CBG), cannabigerolic acid (CBGA), cannabidivarin (CBDV), cannabidibutol (CBD-C4), dihydrocannabidiol (DCBD), tetrahydrocannabivarin (THCV), analogs thereof, and precursors to the foregoing. One method employs phloroglucinol or a phloroglucinol analog as a starting material. The syntheses are stereospecific, efficient, selective, and cost-effective, with little or no potential for generation of THC (()-trans-.sup.9-tetrahydro-cannabinol) or any other psychoactive side product. Telescoped syntheses are also provided, as are new cannabinoids, pharmaceutical formulations, and methods of use.
