A method to lower the degree of halogenation of polyhalogenated pigments was written by Matsuoka, Masaru;Kitao, Teijiro. And the article was included in Shikizai Kyokaishi in 1976.HPLC of Formula: 24407-32-7 This article mentions the following:

In both pigment systems I and II (Z = p-C6H4, p-C6H4C6H4-p) a benzo substituent on both aromatic rings was intermediate between 4 Cl and 4 Br substituents in its effect on increasing the thermal stability as determined by thermogravimetry. Thus, annellation can be considered as an alternative to halogenation to prepare pigments with greater heat resistance, avoiding the toxicity problems associated with polychloro aromatic compounds In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7HPLC of Formula: 24407-32-7).

4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. Indole is an important structural motif of various drugs, therapeutic leads besides its prevalence in numerous natural products, agrochemicals, perfumery, and dyes. Moreover, it is known that it controls biofilm formation. However, the role of indole in the cell has not been fully elucidated.HPLC of Formula: 24407-32-7

Preparation of methylamine was written by Jones, Hilton Ira;Wheatley, Roth. And the article was included in Journal of the American Chemical Society in 1918.Name: 4,5,6,7-Tetrabromoisoindoline-1,3-dione This article mentions the following:

A study of the equations given by Werner to explain the mechanism of the reaction between HCHO and NH₄Cl shows that if the temperature should be kept down and the decomposition of the HCO₂H as It formed should be hastened MeNH₂ should be almost the sole product, a deduction which has been verified by experiment Of 4 experiments, one was a duplication of W.’s, the 2nd was a slow distillation like the first but under 20 mm., in the 3rd the material was refluxed 8 hrs. under atm. pressure before the distillation (also under atm. pressure). while in the 4th the refluxing (4.5 hrs.) and distillation were carried out under 20 mm. Working with 150 g. NH₄Cl and 300 g. of 40% HCHO, the following results were obtained in the 4 experiments, resp.: unchanged NH₄Cl, 46.47, 79.9, 33.5, 27.18; MeNH₂Cl, 70.67, 44.83, 67.60, 82.50; Me₂NH₂Cl, 12.40, 9.66, 17.35, 7.90; non-crystallizing residue, 45.53, 23.53, 64-73, 54.43 g. The sp. gr. and rotations of the distillates and the approx. amounts of HCO₂Me and HCO₂H present were also determined The results all accord with W.’s theory. In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7Name: 4,5,6,7-Tetrabromoisoindoline-1,3-dione).

4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.Name: 4,5,6,7-Tetrabromoisoindoline-1,3-dione

Comparison of the relative cost effectiveness of brominated and chlorinated flame retardants in EPDM was written by Lesniewski, Joseph M.. And the article was included in Proceedings of International Wire and Cable Symposium in 1980.Category: indole-building-block This article mentions the following:

The relative effectiveness of cyclooctadiene-hexachlorocyclopentadiene Diels-Alder diadduct (I) [13560-89-9] and tetrabromophthalimide (II) [24407-32-7] as flame retardants was studied in calcined clay-filled 80:20 (weight) EPDM rubber-polyethylene [9002-88-4] standard formulations (revised NDX 5117) for wire and cable applications. The flame retardant component was removed from the standard formulation (containing 30 parts flame retardant) until 0, 10, 15, 20, or 30% removal of fire retardant was obtained. The 200% modulus was higher and % elongation was slightly lower for formulations containing II. Ratings from the O index test indicated a better response from II than from I in all formulations. The UL-94 flame test indicated that only the standard formula and the formula with 10% removal of II gave a 94-VO rating; the formula containing I burned under UL-94 testing. The VW-1 flame test indicated that the standard loading for I was at its optimum for the system and that further lowering resulted in failure; the amount of II was lowered by 闂?0% before failing the VW-1 test. In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7Category: indole-building-block).

4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. In addition to tryptophan, indigo, and indoleacetic acid, numerous compounds obtainable from plant or animal sources contain the indole molecular structure. More than 200 indole derivatives have already been marketed as drugs or are under advanced stages of clinical trials.Category: indole-building-block
