3-Thiophenethiol, 4-methyl-, also known as 4-Methyl-3-thiophenethiol or 4-Methyl-3-mercaptothiophene, is an organic compound with the chemical formula C5H6S. It is a colorless to pale yellow liquid with a strong, pungent odor. 3-Thiophenethiol, 4-methyl- is a derivative of thiophene, a heterocyclic aromatic compound consisting of a benzene ring with one carbon atom replaced by a sulfur atom. The 4-methyl-3-thiophenethiol features a methyl group attached to the fourth carbon of the thiophene ring and a thiol (-SH) group at the third carbon. It is used as a synthetic intermediate in the production of pharmaceuticals, agrochemicals, and other organic compounds. Due to its reactive nature, it is essential to handle 3-Thiophenethiol, 4-methyl- with care, using appropriate safety measures and protective equipment.

Check Digit Verification of cas no

The CAS Registry Mumber 2527-77-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2527-77:
(6*2)+(5*5)+(4*2)+(3*7)+(2*7)+(1*7)=87
87 % 10 = 7
So 2527-77-7 is a valid CAS Registry Number.

Formation of thiophenethiols by flash vacuum pyrolysis of 1,6,6aλ4-trithiapentalenes

Flammang, Robert,Barbieux-Flammang, Monique,Gerbaux, Pascal,Pedersen, Carl Th.

, p. 1261 - 1264 (2007/10/03)

The thermal behaviour of 1,6,6aλ4-trithiapentalene 3 and some methyl-substituted derivatives 5-7 has been investigated using a combination of flash vacuum pyrolysis (FVP), tandem mass spectrometry (MS-MS) and matrix isolation IR spectroscopy. the main products of the fragmentation (losses of CS and/or CH2=C=S) are shown to be thiophene-3-thiones (or the thiol tautomers) which are also shown to be readily available by direct sulfuration of thiophenes in chemical ionization (CS2 reagent gas) conditions.
