Trimethylsilyl o-bromobenzoate is an organosilicon compound with the chemical formula C10H13BrOSi. It is a colorless to pale yellow liquid that is soluble in common organic solvents. trimethylsilyl o-bromobenzoate is synthesized by the reaction of o-bromobenzoic acid with trimethylsilyl chloride (TMSCl) in the presence of a base, such as pyridine. Trimethylsilyl o-bromobenzoate is primarily used as a protecting group in organic synthesis, particularly for carboxylic acids, due to its stability and ease of removal under mild conditions. It is also employed as an intermediate in the preparation of various pharmaceuticals and agrochemicals. The compound is sensitive to moisture and should be stored under an inert atmosphere to prevent hydrolysis.

Check Digit Verification of cas no

The CAS Registry Mumber 33324-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,2 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33324-32:
(7*3)+(6*3)+(5*3)+(4*2)+(3*4)+(2*3)+(1*2)=82
82 % 10 = 2
So 33324-32-2 is a valid CAS Registry Number.

Benchtop-Stabssle Hypervalent Bromine(III) Compounds: Versatile Strategy and Platform for Air- And Moisture-Stable λ3-Bromanes

We present the first synthesis of air/moisture-stable λ3-bromanes (9and10) by using a cyclic 1,2-benzbromoxol-3-one (BBX) strategy. X-ray crystallography and NMR and IR spectroscopy ofN-triflylimino-λ3-bromane (12) revealed that the bromine(III) center is effectively stabilized by intramolecular R-Br-O hypervalent bonding. This strategy enables the synthesis of a variety of air-, moisture-, and benchtop-stable Br-hydroxy, -acetoxy, -alkynyl, -aryl, and bis[(trifluoromethyl)sulfonyl]methylide λ3-bromane derivatives.
