932-41-2 Usage
Uses
Used in Organic Synthesis:
2,3-Thiophenedicarboxaldehyde is used as a key intermediate in the synthesis of various organic compounds. Its ability to undergo aldol reactions with other organic molecules makes it a valuable building block for creating complex organic structures.
Used in the Synthesis of TIPSEBr2-AntDT:
Specifically, 2,3-Thiophenedicarboxaldehyde is used as a precursor in the synthesis of TIPSE (triisopropylsilylethynyl)-substituted dibromoanthradithiophene (TIPSEBr2-AntDT). 2,3-Thiophenedicarboxaldehyde is of interest in the field of materials science, potentially for applications in organic electronics such as organic solar cells or organic light-emitting diodes (OLEDs), due to its unique electronic properties conferred by the anthradithiophene core and TIPSE substitution.
Check Digit Verification of cas no
The CAS Registry Mumber 932-41-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 2 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 932-41:
(5*9)+(4*3)+(3*2)+(2*4)+(1*1)=72
72 % 10 = 2
So 932-41-2 is a valid CAS Registry Number.

Two chemodivergent anionic domino processes from cyclic α-nitroketones and aromatic aldehydes
Giorgi, Giorgio,Arroyo, Francisco J.,López-Alvarado, Pilar,Menéndez, J. Carlos
experimental part, p. 5582 - 5589 (2011/08/10)
Treatment of cyclic α-nitroketones and aromatic 1,2-dialdehydes with DBU in tetrahydrofuran containing small amounts of water proceeded through two chemodivergent one-pot domino pathways, whose outcome depended on the ring size of the starting nitroketone. Thus, α-nitrocyclohexanone underwent diastereoselective α′-arylmethylenation reactions through a nitroaldol/aldol/reverse nitroaldol mechanism. On the other hand, α-nitrocycloheptanone and α-nitrocyclooctanone afforded 2-nitroindane-1,2-diols containing three contiguous stereocenters in a highly diastereoselective fashion through a nitroaldol/retro-Dieckmann/intramolecular nitroaldol process.
