Bromomethane-d2, also known as CH2Br2-d2 or bromomethane-D2 98 atom % D, is a deuterated chemical compound with the molecular formula CH2Br2-d2. It is a halogenated derivative of methane, where two hydrogen atoms are replaced by deuterium atoms (hydrogen atoms with an additional neutron). BROMOMETHANE-D2 98 ATOM % D is primarily used as a reagent in organic synthesis, particularly in the preparation of various organic compounds and as a tracer in chemical reactions. Due to its high deuterium content (98%), it is also utilized in spectroscopic studies and as a non-toxic alternative to the non-deuterated bromomethane in certain applications. Bromomethane-d2 is a colorless liquid with a density of 2.14 g/mL and a boiling point of 40.1°C. It is sensitive to light and should be stored in a dark, cool place to prevent decomposition.

4960-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4960-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,6 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4960-89:
(6*4)+(5*9)+(4*6)+(3*0)+(2*8)+(1*9)=118
118 % 10 = 8
So 4960-89-8 is a valid CAS Registry Number.

Metal ions do not play a direct role in the formation of carbon-carbon triple bonds during reduction of trihaloalkyls by CrII or V II

Levy, Ophir,Bino, Avi

supporting information, p. 15944 - 15947 (2013/02/23)

Carbyne radicals: Reactions of trihaloalkyl compounds with Cr2+ or V2+ in aqueous solutions yield alkynes and other products. Stepwise halogen abstractions from the trihaloalkyls form alkyl carbyne triradicals in solution. These radicals undergo coupling reactions, producing triply bonded alkyne molecules (see scheme). This process is not metal-assisted and does not occur in the coordination sphere of the metal ions.
