Mass spectrometry distinguishable synthetic compounds, libraries, and methods thereof

A method comprising:

• using logic circuitry to:
• assign each of a plurality of subgroups to only one position in a sequence order for a plurality of prospective molecules, each of the plurality of subgroups exhibiting a mass spectrometry characteristic that is distinguishable from other subgroups in the plurality;
• select a plurality of molecules from the plurality of prospective molecules based on each including a unique sequence of a subset of m subgroups of the plurality of subgroups in the order of their assigned positions and each exhibiting a mass spectrometry characteristic that is distinguishable by a threshold value from mass spectrometry characteristics of other molecules of the plurality, wherein each of the plurality of subgroups are selected from a functional group and a monomer;
• assign each of the plurality of molecules to only one position in a sequence order of n number of positions for a plurality of synthetic compounds forming a library;
• define and store, as data in a memory circuit of the logic circuitry, each of the plurality of synthetic compounds as a unique sequence of a subset of n molecules of the plurality of molecules, one from each position in the sequence, and coupled together in the order of their assigned positions in the unique sequence and with cleavable groups positioned between each of the n molecules such that the n molecules are separatable from one another and the synthetic compounds are sequenceable via cleavage of the cleavable groups, mass spectrometry, and the distinguishable mass spectrometry characteristics of the n molecules;
• communicate the data defining the plurality of synthetic compounds to other circuitry;
• and
• using the other circuitry to receive the data defining the plurality of synthetic compounds and to form the plurality of synthetic compounds via coupling chemistry and based on the data defining the plurality of synthetic compounds, wherein the formed plurality of synthetic compounds are identifiable from one another via cleavage of the cleavable groups and the distinguishable mass spectrometry characteristics of the subset of n molecules as defined in the data, wherein the distinguishable mass spectrometry characteristics of the n molecules identify the n molecules, the order of the n molecules in each of the plurality of synthetic compounds, and the order of m subgroups forming each of the n molecules.
