Selenous acid dimethyl ester, also known as dimethyl selenous acid or selenous acid dimethyl ester, is an organoselenium compound with the chemical formula (CH3)2SeO2. It is a colorless, oily liquid that is soluble in organic solvents and has a pungent odor. selenous acid dimethyl ester is synthesized by the reaction of dimethyl sulfate with selenium dioxide or selenous acid. Selenous acid dimethyl ester is an important intermediate in the synthesis of various organoselenium compounds, which have applications in the pharmaceutical, agrochemical, and materials science industries. It is also used as a reagent in organic synthesis and as a precursor for the preparation of other selenium-containing compounds. Due to its reactivity and potential toxicity, it is essential to handle selenous acid dimethyl ester with care and in accordance with proper safety protocols.
The CAS Registry Mumber 7600-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 0 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7600-22: (6*7)+(5*6)+(4*0)+(3*0)+(2*2)+(1*2)=78 78 % 10 = 8 So 7600-22-8 is a valid CAS Registry Number.
