4114-31-2 Usage

Chemical Properties

Off-white crystals.

Uses

Different sources of media describe the Uses of 4114-31-2 differently. You can refer to the following data:
1. Synthetic intermediate.
2. Prepare 4-phenylurazole from ethyl carbazate and then oxidize the urazole with gaseous dinitrogen tetroxide to yield 4-phenyl-1,2,4-tri- azoline-3,5-dione la. Modification of the ethyl carbazate procedure in which analytically pure monoalkylhydrazine hydrochlorides were isolated in greater than 90% yield, starting from a ketone or aldehyde. Treatment of primary amines is with chloroamine or hydroxylamine-0-sulfonic acid and the condensation of a carbonyl compound with ethyl carbazate. The FeCl 3 -catalyzed reaction of ethyl carbazate (2 b) proceeded readily to give β-hydroxyester 3 b in better yield. A new one-pot neat synthesis of some 5-aryl-2,4-dihydro-3H-1,2,4-triazol-3-ones through cyclocondensation of ethyl carbazate with aryl nitriles catalyzed by DMAP as an efficient and basic nucleophilic catalyst is described.

Hazard

Irritant.

Purification Methods

Fractionate the carbazate using a Vigreux column (p 11) until the distillate crystallises [Allen & Bell Org Synth Coll Vol III 404 1955, Beilstein 3 IV 174].

Check Digit Verification of cas no

The CAS Registry Mumber 4114-31-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,1 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4114-31:
(6*4)+(5*1)+(4*1)+(3*4)+(2*3)+(1*1)=52
52 % 10 = 2
So 4114-31-2 is a valid CAS Registry Number.

Paragraph 0025; 0046; 0047, (2017/06/13)

The invention discloses a novel method for synthesizing a 1,2,3-thiadiazole-5-formamidine compound. The target compound shown in general formula TDCA is prepared from a compound as shown in general formula M by virtue of a methylation reaction. The target component as shown in the general formula M is prepared from a compound as shown in general formula A and a compound as shown in general formula N by virtue of a condensation reaction, wherein during the methylation reaction, preferably, a catalyst is an organic metallic catalyst consisting of cuprous iodide and a ligand, namely 2,2,6,6-tetramethyl-3,5-heptadione; during the reaction, preferably, dimethylbenzene is taken as a solvent, and the optimum reaction temperature is 100-140 DEG C. The method disclosed by the invention is high in yield and more environment-friendly (as shown in Specification).
