77185-78-5 Usage
General Description
ETHYL 3,5-DIBROMO-1H-INDOLE-2-CARBOXYLATE is a chemical compound belonging to the group of indole carboxylic acids and derivatives. Its molecular formula is C11H8Br2NO2 and it is commonly used in organic synthesis. The presence of two bromine atoms makes it a useful reagent for cross-coupling reactions. In addition to its use in synthesis, this compound is studied for potential biological activities. As with most chemical substances, precautions should be taken to avoid skin and eye contact, inhalation or ingestion. It is typically available as a solid and should be stored in a cool, dry place.
Check Digit Verification of cas no
The CAS Registry Mumber 77185-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,8 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77185-78:
(7*7)+(6*7)+(5*1)+(4*8)+(3*5)+(2*7)+(1*8)=165
165 % 10 = 5
So 77185-78-5 is a valid CAS Registry Number.

Various substituted-7,12-dihydroindolobenzodiazepines (4a-e) have been prepared from the corresponding 3-aminoindoles (1a-e) through Ullmann reaction with o-chloroaniline, acylation of the resulting 3-(o-aminophenylamino)indoles (2a-e) and cyclization of amides (3a-e) with POCl3.Similar systems have also been synthesized from ethyl 3-bromoindole-2-carboxylates (6a-e).The bromo esters react with o-phenylenediamine to give ethyl 3-(o-aminophenylamino)indole-2-carboxylates (7a-e) which undergo cyclization in the presence of PPA to yield 5,6,7,12-tetrahydroindolobenzodiazepin-6-ones (8a-e).
