This invention describes an amidation process whereby amino acids of the Formulae IIA or IIB can be activated and treated with an amine in the presence of a base to yield amides of the Formula, without loss of optical purity. The production display includes a simulated model corresponding to the oil and gas production system, and the properties display includes fluid properties corresponding to the oil and gas production system. The security tag also includes a transmitter designed to covertly transmit security tag data to a receiver.
