Title: A Systematic Method for the Targeted Discovery of Chemical Attribution Signatures – Application to Isopropyl Bicyclophosphate Production Abstract: Potential attribution signatures for the synthesis of a highly toxic bicyclophosphate, 4-isopropyl-2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane 1-oxide (Isopropyl Bicyclophosphate or IPBCP) were discovered using a trilateral synthetic, analytical, and statistical approach. Initially, five synthetic routes were... MORE
