Uses

5-(Trifluoromethyl)thiophene-2-carboxylic Acid is a useful reactant for the synthesis of substituted 1,?2,?3-?triazoles as NR2B-?selective NMDA modulators.

Check Digit Verification of cas no

The CAS Registry Mumber 128009-32-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,0 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128009-32:
(8*1)+(7*2)+(6*8)+(5*0)+(4*0)+(3*9)+(2*3)+(1*2)=105
105 % 10 = 5
So 128009-32-5 is a valid CAS Registry Number.

SYNTHESIS AND POLYMERISATION OF ETHYNYLTHIOPHENES AND ETHYNYLFURANS CONTAINING TRIFLUORMETHYL GROUPS

Fluorination of thiophenedicarboxylic acid with sulfur tetrafluoride in the presence of anhydrous hydrogen fluoride provided mono and bis(trifluoromethyl)thiophenes in moderate yields.Ethynylthiophenes and ethynylfurans containing trifluoromethyl groups were prepared via 2,2-dichloro-1-fluorovinyl compounds.In polymerizations using transitions metal catalysts, 3-ethynylthiophenes gave polymers in high yields, which were soluble in THF and/or fluorocompounds, while 2-ethynylthiophenes polymerized in low yields.In γ-ray induced polymerization, only 2,5-bis(trifluoromethyl)-3-ethynylthiophene afforded the corresponding polymers.Thermal decomposition temperatures of polymers obtained increased by introduction of the trifluoromethyl groups as well as the methyl groups.
