Benzenemethanol, α-(chloromethyl)-3,4-dimethoxy-, also known as 3,4-dimethoxybenzyl chloride or DMBC, is an organic compound with the chemical formula C9H11ClO2. It is a colorless to pale yellow liquid with a molecular weight of 184.64 g/mol. Benzenemethanol, a-(chloromethyl)-3,4-dimethoxy- is derived from benzyl alcohol, where the hydroxyl group is replaced by a chloromethyl group, and two methoxy groups are attached to the benzene ring at the 3 and 4 positions. DMBC is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds due to its reactivity and versatility. It is also known for its potential use as a protecting group in organic synthesis. However, it is important to note that DMBC is a hazardous substance and should be handled with care due to its potential health risks and environmental impact.

Check Digit Verification of cas no

The CAS Registry Mumber 4973-20-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4973-20:
(6*4)+(5*9)+(4*7)+(3*3)+(2*2)+(1*0)=110
110 % 10 = 0
So 4973-20-0 is a valid CAS Registry Number.

Efficient synthesis of chlorohydrins using ClCH2MgCl·LiCl

Nishimura, Rodolfo H.V.,Toledo, Fabiano T.,Lopes, Jo?o L.C.,Clososki, Giuliano C.

, p. 287 - 290 (2013/02/23)

The mixed lithium-magnesium carbenoid ClCH2MgCl·LiCl was easily generated in THF through the reaction of chloroiodomethane with i-PrMgCl·LiCl at -78 °C. This reagent reacts well with a number of aldehydes to give the corresponding chlorohydrins in good yields.
