Picryl azide, also known as 2,4,6-trinitrophenyl azide or TNPA, is a highly sensitive and powerful chemical compound with the molecular formula C6HN8O7. It is derived from picric acid (2,4,6-trinitrophenol) and is commonly used as a primary explosive in detonators due to its high sensitivity to impact, friction, and heat. Picryl azide is a pale yellow crystalline solid that is soluble in acetone and ethanol but insoluble in water. It is known for its potential use in initiating high explosives and is often employed in military and industrial applications. However, due to its extreme sensitivity and hazardous nature, handling and storage of picryl azide require strict safety precautions and specialized knowledge.

1600-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1600-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1600-31:
(6*1)+(5*6)+(4*0)+(3*0)+(2*3)+(1*1)=43
43 % 10 = 3
So 1600-31-3 is a valid CAS Registry Number.

Thermal behavior, decomposition mechanism and thermal safety of 5,7-diamino-4,6-dinitrobenzenfuroxan (CL-14)

Fu, Xiao-Long,Fan, Xue-Zhong,Wang, Bo-Zhou,Huo, Huan,Li, Ji-Zhen,Hu, Rong-Zu

, p. 993 - 1001 (2016/07/06)

Thermal decomposition kinetics and mechanism of the high-energetic material 5,7-diamino-4,6-dinitrobenzenfuroxan (CL-14) were determined by differential scanning calorimetry (DSC), rapid scanning Fourier transform infrared spectroscopy, and simultaneous thermogravimetric and DSC analyses, coupled with FT-IR and mass spectroscopy. To evaluate the thermal safety of 5,7-diamino-4,6-dinitrobenzenfuroxan (CL-14), its specific heat capacity (Cp) was measured by DSC, and thermal conductivity (λ) was estimated. Kinetic parameters and heat of exothermic decomposition reaction of CL-14 were obtained by analysis of DSC curves. Kinetic parameters used to evaluate the thermal safety of CL-14, such as self-accelerating decomposition temperature (TSADT), critical temperature of thermal explosion (Tb) and impact sensitivity (H50), were obtained. Results showed that for CL-14, TSADT?=?282.0?°C and Tb?=?307.9?°C, whereas H50?=?39.79?cm, revealing that CL-14 had better thermal safety and heat resistance than HMX, RDX and GNTO.

The activation of SNAr reactions by the superstrong electron-withdrawing substituent CF3S(O)=NSO2CF3

Boiko, V. N.,Kirii, N. V.,Yagupolskii, L. M.

, p. 119 - 124 (2007/10/03)

The chlorine lability of the 2-nitrochlorobenzene derivative which contains the superstrong electron-withdrawing substituent CF3S(O)=NSO2CF3 in position 4 has been compared with the analogous 4-trifluoromethylsulphonyl derivative and picryl chloride in nucleophilic substitution.During interaction with hard nucleophilic agents, the effect of one superstrong substituent approximately corresponds to the influence of two nitro groups in positions 2 and 4.With soft reagents, picryl chloride is more active than the compound containing the CF3S(O)=NSO2CF3 group, polarizable only with difficulty.

Influence of strain on chemical reactivity. Relative reactivity of torsionally strained double bonds in 1,3-dipolar cycloadditions
