'amino-synthetic' is a modern English compound formed from the combining form 'amino-' (relating to amines or amino acids) and 'synthetic' (relating to synthesis or artificially produced).

'amino-' developed in chemical nomenclature in the 19th century from 'amine' (itself coined from 'ammonia' via modern chemistry terms), while 'synthetic' comes from Greek 'synthētikos' via Latin/French into English; these elements were combined in modern scientific English to form technical compounds such as 'amino-synthetic'.

Initially, 'amino-' identified groups derived from ammonia/amine chemistry and 'synthetic' meant 'made by synthesis'; combined, the term has come to mean 'produced by synthetic methods that specifically involve amino chemistry' and is used for describing materials or processes that are artificial and amino-related.
