1-Propyn-1-ol, 4-methylbenzenesulfonate is a chemical compound that can be described as a derivative of 1-propyn-1-ol, where a 4-methylbenzenesulfonate group is attached to it. 1-Propyn-1-ol, 4-methylbenzenesulfonate is characterized by the presence of a propargyl alcohol moiety (1-propyn-1-ol) and a 4-methylbenzenesulfonate group, which is a sulfonate ester derived from toluene. The combination these of two functional groups results in a molecule with unique chemical properties, making it potentially useful in various applications, such as in the synthesis of pharmaceuticals, agrochemicals, or other specialty chemicals. The specific reactivity and solubility of 1-Propyn-1-ol, 4-methylbenzenesulfonate can be influenced by the presence of the electron-withdrawing sulfonate group and the electron-donating alkyne and hydroxyl groups, which can affect its behavior in different chemical reactions and its interactions with other molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 94957-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,9,5 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 94957-44:
(7*9)+(6*4)+(5*9)+(4*5)+(3*7)+(2*4)+(1*4)=185
185 % 10 = 5
So 94957-44-5 is a valid CAS Registry Number.

Single-crystal molecular structure determinations and theoretical calculations on alkynyl sulfonate and carboxylate esters

Stang, Peter J.,Crittell, Charles M.,Arif, Atta M.,Karni, Miriam,Apeloig, Yitzhak

, p. 7461 - 7470 (1991)

The single-crystal X-ray structures of propynyl tosylate, 4, and of ethynyl benzoate, 5, were determined. Both esters are essentially linear acetylenes with O≡C-O bond angles of 174.7° and 177.6°, respectively. The C≡C-O acetylenie-oxygen bond length is 1
