Trimethylsilylbenzoxazolone, also known as TMSBO, is a chemical reagent used in organic synthesis, particularly for the protection of carbonyl groups. It is formed by the reaction of benzoxazolone with trimethylsilyl chloride, resulting in a laktim structure. This laktim form is a cyclic amide that can readily react with carbonyl compounds, such as aldehydes and ketones, to form stable silyl ethers. These silyl ethers are useful in various chemical transformations, as they can be selectively removed under mild conditions, allowing for the controlled manipulation of the carbonyl group. The trimethylsilylbenzoxazolone reagent is appreciated for its ease of use, selectivity, and the stability of the resulting protected compounds, making it a valuable tool in organic chemistry.

52726-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52726-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,7,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.Calculate Digit Verification of CAS Registry Number 52726-91:
(7*5)+(6*2)+(5*7)+(4*2)+(3*6)+(2*9)+(1*1)=127
127 % 10 = 7
So 52726-91-7 is a valid CAS Registry Number.
