20428-76-6 Usage

General Description

Methyl Bromodichloroacetate is a halogenated organic compound with the chemical formula C3H3BrCl2O2. It is a colorless liquid with a pungent odor and is a powerful lachrymator, meaning it causes intense eye irritation. Methyl Bromodichloroacetate is primarily used as an intermediate in the manufacturing of pharmaceuticals, agrochemicals, and other organic compounds. It is also used as a pesticide and herbicide in agriculture. The compound is highly reactive and can undergo various chemical reactions, making it useful in organic synthesis. However, it is also considered toxic and environmentally harmful, and therefore requires careful handling and disposal.

Check Digit Verification of cas no

The CAS Registry Mumber 20428-76-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,2 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20428-76:
(7*2)+(6*0)+(5*4)+(4*2)+(3*8)+(2*7)+(1*6)=86
86 % 10 = 6
So 20428-76-6 is a valid CAS Registry Number.

Occurrence, synthesis, and mammalian cell cytotoxicity and genotoxicity of haloacetamides: An emerging class of nitrogenous drinking water disinfection byproducts

Plewa, Michael J.,Muellner, Mark G.,Richardson, Susan D.,Fasano, Francesca,Buettner, Katherine M.,Woo, Yin-Tak,Mckague, A. Bruce,Wagner, Elizabeth D.

, p. 955 - 961 (2008/03/31)

The haloacetamides, a class of emerging nitrogenous drinking water disinfection byproduct (DBPs), were analyzed for their chronic cytotoxicity and for the induction of genomic DNA damage in Chinese hamster ovary cells. The rank order for cytotoxicity of 13 haloacetamides was DIAcAm > IAcAm > BAcAm > TBAcAm > BIAcAm > DBCAcAm > CIAcAm > BDCAcAm > DBAcAm > BCAcAm > CAcAm > DCAcAm > TCAcAm. The rank order of their genotoxicity was TBAcAm > DIAcAm ≈ IAcAm > BAcAm > DBCAcAm > BIAcAm > BDCAcAm > CIAcAm > BCAcAm > DBAcAm > CAcAm > TCAcAm. DCAcAm was not genotoxic. Cytotoxicity and genotoxicity were primarily determined by the leaving tendency of the halogens and followed the order I > Br > > Cl. With the exception of brominated trihaloacetamides, most of the toxicity rank order was consistent with structure-activity relationship expectations. For di- and trihaloacetamides, the presence of at least one good leaving halogen group (I or Br but not Cl) appears to be critical for significant toxic activity. Log P was not a factor for monohaloacetamides but may play a role in the genotoxicity of trihaloacetamides and possible activation of dihaloacetamides by intracellular GSH and -SH compounds. With the advent of the U.S. EPA Stage 2 DBP regulations, water utilities are considering the use of disinfectants that are alternatives to chlorine. The use of these alternative disinfectants will shift the distribution of DBP chemical classes. The emergence of new, highly toxic iodinated, nitrogenous DBPs, as illustrated by the discovery of bromoiodoacetamide as a new DBP, underscores the importance of comparative toxicity studies to assist in the overall goal of safer drinking water practice.
