Valeric acid trimethylsilyl ester, also known as pentanoic acid trimethylsilyl ester, is a chemical compound with the molecular formula C8H18O2Si. It is a colorless liquid that is derived from the esterification of valeric acid with trimethylsilyl chloride. Valeric acid trimethylsilyl ester is commonly 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 utilized in the preparation of various derivatives and as a reagent in the synthesis of pharmaceuticals and other specialty chemicals. The trimethylsilyl group provides a stable, non-polar environment that can protect the carboxylic acid functionality from unwanted reactions, while also facilitating certain transformations in organic chemistry.

26429-16-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26429-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,2 and 9 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 26429-16:
(7*2)+(6*6)+(5*4)+(4*2)+(3*9)+(2*1)+(1*6)=113
113 % 10 = 3
So 26429-16-3 is a valid CAS Registry Number.

Partition coefficients of ketones, phenols, aliphatic and aromatic acids, and esters in n-hexane/nitromethane

Kotowska, Urszula,Isidorov, Valery A.

scheme or table, p. 813 - 824 (2012/03/27)

Liquid-liquid partition is used in sample preparation and in countercurrent and liquid-liquid chromatographic separations. Partition coefficients are widely used in toxicology, environmental, and analytical chemistry. The K hn determination procedure for the n-hexane/ nitromethane system was optimized and partition coefficients for 99 ketones, esters and trimethylsilyl derivatives of phenols, aliphatic and aromatic acids were determined. For 130 compounds, Khn values were predicted using mathematical relationships between Khn and other physicochemical and structural parameters. Versita Sp. z o.o.
