14835-47-3 Usage
General Description
1,2,4-Butanetriol, triacetate, also known as BTTA, is a chemical compound commonly used as a plasticizer for the manufacture of safety glass. It is a clear, odorless, and viscous liquid that is not soluble in water but can dissolve in common organic solvents. It is efficient in enhancing the properties of plastic materials, providing better flexibility and durability. This chemical is produced by acetylating 1,2,4-butanetriol and is considered stable under normal temperatures and pressures. However, exposure to this chemical can cause skin and eye irritation in humans, and it should therefore be handled with care. Furthermore, it should be stored in cool and dry places, away from heat sources and sunlight to prevent degradation.
Check Digit Verification of cas no
The CAS Registry Mumber 14835-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,8,3 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14835-47:
(7*1)+(6*4)+(5*8)+(4*3)+(3*5)+(2*4)+(1*7)=113
113 % 10 = 3
So 14835-47-3 is a valid CAS Registry Number.

Oxidative Cyclization of Some γ- and δ-Hydroxy Olefins Induced by Tellurium Dioxide
Bergman, Jan,Engman, Lars
, p. 5196 - 5200 (1981)
TeO2 reacted with 2 equiv of a γ- or δ-hydroxy olefin in acetic acid containing LiCl.The resulting dialkyltellurium dichlorides are derivatives of furan, tetrahydrofuran, and 2,3-dihydrobenzofuran, formed via an internal cyclization.The dialkyltellurium dichlorides were reduced to their corresponding dialkyltellurides with use of Na2S2O5 or hydrazine hydrate.A mechanism is postulated involving an electrophilic attack by a solubilized tellurium species followed by an intramolecular nucleophilic attack by a hydroxy group.An analysis of the vicinal proton coupling constants indicated one preferred conformation of the dialkyltellurium dichlorides, where the oxygen atoms of the furan rings are coordinated to tellurium.
