34981-11-8 Usage

General Description

2,6-Diamino-3,5-dinitropyridine, often abbreviated as DADNP, is a compound with both nitro and amino groups. This high-nitrogen compound exhibits explosive properties, making it a component in some types of energetic materials. It has a light yellow crystal structure and is known for its stability, high density, and great sensitivity to impact or friction. DADNP is often used in the creation of less sensitive, more environmentally friendly explosives. However, it should be handled with caution due to its potential risk and the necessary safety procedures.

Check Digit Verification of cas no

The CAS Registry Mumber 34981-11-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,9,8 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34981-11:
(7*3)+(6*4)+(5*9)+(4*8)+(3*1)+(2*1)+(1*1)=128
128 % 10 = 8
So 34981-11-8 is a valid CAS Registry Number.

, p. 1652 - 1659 (2009)

A simple and efficient route for preparing 2,3,5,6-tetraaminopyridine hydrochloride salt (TAP-3HCl.H2O) was introduced in this paper. The title compound was synthesized, as usual, in two steps (nitration and hydrogenation) with a total yield of

Nitration method for preparing 2, 6-diamido-3, 5-binitro pyridine by ultrafine zeolite-based micro-channel reaction

Page/Page column 6-9, (2019/03/08)

The invention provides a nitration method for preparing 2, 6-diamido-3, 5-binitro pyridine by ultrafine zeolite-based micro-channel reaction. The nitration method includes the steps: heating and uniformly mixing crushed sodium amide, decahydronaphthalene and p-toluidine, performing microwave heating reaction on mixture and pyridine by a Y-shaped micro-channel reactor, and filtering and recrystallizing the mixture and the pyridine to obtain 2, 6-diamido pyridine; blowing ultrafine HZSM-5 catalysts into an outlet channel of the Y-shaped micro-channel reactor, placing the modified Y-shaped micro-channel reactor into an ice-water bath, leading the 2, 6-diamido pyridine and dichloromethane solution containing nitrogen pentoxide into the Y-shaped micro-channel reactor, accelerating flow and rapidly increasing temperature to reach reaction temperature to obtain a 2, 6-diamido-3, 5-binitro pyridine crude product; secondarily recrystallizing, filtering and drying the 2, 6-diamido-3, 5-binitro pyridine crude product, adding the crude product into distilled water, boiling the distilled water and performing dimethyl sulfoxide secondary crystallization to obtain the 2, 6-diamido-3, 5-binitro pyridine with high yield and purity.

2,6-Diamino-3,5-dinitropyridine 1-oxide has been prepared by mixed acid nitration of 2,6-diaminopyridine, followed by oxidation using hydrogen peroxide in acetic acid. 3,5-Dinitro-2,4,6-triaminopyridine has been prepared by oxidative amination of 2-chloro-3,5-dinitropyridine or 2,6-diamino-3,5-dinitropyridine using potassium permanganate in liquid ammonia, or by "vicarious nucleophilic amination" of 2,6-diamino-3,5-dinitropyridine using hydroxylamine in aqueous potassium hydroxide. 3,5-Dinitro-2,4,6-triaminopyridine 1-oxide has been prepared by oxidation of 3,5-dinitro-2,4,6-triaminopyridine using hydrogen peroxide in acetic acid, and by "vicarious nucleophilic amination" of 2,6-diamino-3,5-dinitropyridine 1-oxide. Nmr spectroscopy and single crystal X-ray diffraction studies have shown that these compounds have the planar structures and intra- and inter-molecular hydrogen bonding necessary to confer on the materials the high density, the thermal and chemical stability, and the explosive insensitivity required for new insensitive energetic materials.
