Pentanoic acid, 2,2,2-trifluoroethyl ester, also known as 2,2,2-trifluoroethyl pentanoate, is an organic compound with the chemical formula C7H11F3O2. It is an ester derived from pentanoic acid (valeric acid) and 2,2,2-trifluoroethanol. This colorless liquid is characterized by its unique chemical structure, which includes a five-carbon alkyl chain (pentyl) attached to a carboxyl group and a 2,2,2-trifluoroethyl group. The trifluoroethyl moiety is a fluorinated derivative of an ethyl group, which imparts unique properties to the molecule, such as increased lipophilicity and potential reactivity due to the presence of fluorine atoms. Pentanoic acid, 2,2,2-trifluoroethyl ester is primarily used in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals, where its fluorinated nature can influence the physicochemical properties and biological activity of the final products.

Check Digit Verification of cas no

The CAS Registry Mumber 1651-34-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1651-34:
(6*1)+(5*6)+(4*5)+(3*1)+(2*3)+(1*4)=69
69 % 10 = 9
So 1651-34-9 is a valid CAS Registry Number.

Preparation of Enantiomerically Enriched α-Hydroxystannanes via Enzymatic Resolution

Chong, J. Michael,Mar, Eduardo K.

, p. 5683 - 5686 (1991)

The porcine pancreatic lipase (PPL) catalyzed esterifications of α-hydroxystannanes RCH(OH)SnMe3 (R = Me, Et) and MeCH(OH)SnEt3 with 2,2,2-trifluoroethyl valerate afford good yields and excellent enantiomeric (>95 percent ee) purities of the (S)-valerate and the (R)-α-hydroxystannane.Key Words: α-alkoxystannanes; enantiomerically enriched; enzymatic esterification; porcine pancreatic lipase.

Novel Synthetic Reactions Using Bis(2,2,2-trifluoroethoxy)triphenylphosphorane

Kubota, Toshio,Miyashita, Satoshi,Kitazume, Tomoya,Ishikawa, Nobuo

, p. 5052 - 5057 (2007/10/02)

Alkoxy-or (acyloxy)(2,2,2-trifluoroethoxy)triphenylphosphoranes which were prepared in situ by the ligand exchange of bis(2,2,2-trifluoroethoxy)triphenylphosphorane with alcohols or carboxylic acids were found to behave as potential alkylating or acylating reagents for the preparation of a variety of esters, amides, sulfides, and ketones.
