141-86-6 Usage

Uses

Different sources of media describe the Uses of 141-86-6 differently. You can refer to the following data:
1. 2,6-Diaminopyridine can be used to synthesize pentamidine derivatives which show antitumor activities and DNA binding activities. It can also be used to synthesize N-monocarbamoyl derivatives of symmetrical diamines with antiviral activity. Its derivatives can be used as models of molecular sensor for nucleic acid base detection.
2. 2,6-Diaminopyridine, used as a pharmaceutical intermediate and a hair dye coupler in oxidation/permanent formulations.

Chemical Properties

Off-white crystal powder/granuale

Safety Profile

Poison by intravenous and intraperitoneal routes. Mutation data reported. When heated to decomposition it emits toxic fumes of NOx.

Check Digit Verification of cas no

The CAS Registry Mumber 141-86-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 141-86:
(5*1)+(4*4)+(3*1)+(2*8)+(1*6)=46
46 % 10 = 6
So 141-86-6 is a valid CAS Registry Number.

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.
