Vertellus completes DEET expansion

by Marc S. Reisch
April 18, 2016 | APPEARED IN VOLUME 94, ISSUE 16

CORRECTION: This story was updated on April 25, 2016, with the correct structure of DEET.

Vertellus Specialties has completed an 80% expansion of capacity for the insect repellent N,N-diethyl-m-toluamide (DEET) at its Greensboro, N.C., site. The expansion is intended to meet growing demand prompted by recent outbreaks of the mosquito-borne Zika virus. The Centers for Disease Control & Prevention just concluded definitively that the outbreak of microcephaly plaguing Brazil is caused by Zika.

I must be the 100th person to say..."the structure is not DEET"...it's more like "N-ethyl-3,​4-​dihydro-​3,​7-​dimethyl-isoquinolinone" and it is novel, without a CAS number, having not been disclosed previously!

Your article is showing 2-ethyl-3,7-dimethyl-3,4-dihydroisoquinolin-1(2H)-one, not N,N-diethyl-m-toluamide. This formula has an extra bond ortho to the carbonyl.

Yes, the structure is incorrect. We'll fix it shortly.
Marc Reisch (April 26, 2016 10:07 AM)
The structure is now correct.
