Chemistry

An analytical method for MPT's detection has been reported.^[2] In 2019, Chadeayne et al. published the crystal structure of MPT.^[3] The authors describe the structure as "...a single molecule in the asymmetric unit, with an indole group that demonstrates a mean deviation from planarity of 0.015 A°."
