28165-57-3 Usage
Uses
Used in Environmental Testing and Research:
2,3,6-Tribromophenol is used as a standard for environmental testing and research. It plays a crucial role in the determination of urinary bromophenols (BrPs) as potential biomarkers for human exposure to polybrominated diphenyl ethers (PBDEs). The analysis is typically performed using gas chromatography-tandem mass spectrometry (GC-MS/MS), which allows for accurate and sensitive detection of these compounds in environmental and biological samples.
Used in Plant Growth Regulation:
2,3,6-Tribromophenol is also utilized as a plant growth regulator. It can influence various aspects of plant growth and development, such as cell division, elongation, and differentiation. By modulating the levels of 2,3,6-TRIBROMOPHENOL in the growth medium, researchers and agriculturists can study its effects on plant growth and potentially develop strategies to improve crop yields and quality.
Check Digit Verification of cas no
The CAS Registry Mumber 28165-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,6 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28165-57:
(7*2)+(6*8)+(5*1)+(4*6)+(3*5)+(2*5)+(1*7)=123
123 % 10 = 3
So 28165-57-3 is a valid CAS Registry Number.

Ortho-Specific Bromination of Phenols
Schmitz, Ernst,Pagenkopf, Ingeborg
, p. 998 - 1006 (2007/10/02)
Phenol as well as 3-substituted phenols are brominated exclusively in the ortho positions by N.N-dibromomethylamine, yielding 2.6-dibrominated phenols in excellent yields.Phenols bearing an ortho-substituent need N-bromomethylamine as the brominating agent to take up one bromine atom into the free ortho-position. para-Bromination is not observed in either case. 1-Naphthol gives 2-bromo-1-naphthol, 8-hydroxyquinoline gives 7-bromo-8-hydroxyquinoline with 80percent and 98percent yield respectively. ortho-Specific chlorination of phenols was carried out in some cases using N-chloro-alkylamines.
