Metal chelated and halogen substitution of the triazol ring make for a particularly heat sensitive material. Azido and nitro derivatives have been employed as high explosives. No matter the derivative these materials should be treated as explosives.
Safety Profile
Low toxicity by
ingestion and skin contact. A skin and eye
irritant. An unstable explosive. When heated
to decomposition it emits toxic vapors of
NOx.
Check Digit Verification of cas no
The CAS Registry Mumber 932-64-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 932-64:
(5*9)+(4*3)+(3*2)+(2*6)+(1*4)=79
79 % 10 = 9
So 932-64-9 is a valid CAS Registry Number.

Synthesis and thermal decomposition of 15N-labelled NTO
Fan, Leimin,Dass, Chhabil,Burkey, Theodore J.
, p. 87 - 94 (2007/10/03)
5-Nitro-2,4-dihydro-3H-1,2,4-triazol-3-one (NTO) has been synthesized in good yield with 15N at the 1 and 2 positions. The N-H coupling provides unequivocal assignments for 1H and 15N NMR spectra and the acidic proton. The products of thermal decomposition at 270 °C were identified spectroscopically. NMR spectra reveal that thermal decomposition results in the formation of 2,4-dihydro-3H-1,2,4-triazol-3-one and ammonia (the latter observed as ammonium ion). The production of ammonia from the thermal decomposition of an energetic material is unprecedented. The gas products HCN, 15N14N, 15N2 and CO were detected by mass spectrometry. Some possible mechanisms of thermal decomposition are discussed.
