13257-81-3 Usage
General Description
4-Trimethylsiloxypentan-3-one is an organosilicon compound that is primarily used in research laboratories for synthesis and chemical reactions. This chemical, like many other organosilicon compounds, is characterized by its stability and reactivity. It is typically a clear, colorless liquid at room temperature, although its exact physical properties can vary depending on the specific conditions and its purity. It is always critical to handle this and similar lab chemicals properly, as they can pose hazards in case of improper handling or disposal. The 'trimethylsiloxy' part of the molecule includes a silicon atom bonded to three methyl groups and an oxygen atom, making this compound interesting for research in a variety of scientific fields.
Check Digit Verification of cas no
The CAS Registry Mumber 13257-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13257-81:
(7*1)+(6*3)+(5*2)+(4*5)+(3*7)+(2*8)+(1*1)=93
93 % 10 = 3
So 13257-81-3 is a valid CAS Registry Number.

Studies towards the synthesis of (+)-ptilomycalin A; stereoselective N-acyliminium ion coupling reactions to enantiopure C-2 substituted lactams

Highly stereoselective N-acyliminium ion coupling reactions of β-ketoester derived silyl enol ethers with enantiopure lactams derived from (S)-malic acid are reported. This reaction type is applied in the synthesis of the enantiopure C-2 substituted lactam 27, a plausible intermediate in a projected synthesis of ptilomycalin A.
