3-chloro-1-(2,3,4,5-tetramethyl-phenyl)-propan-1-one is a synthetic organic compound characterized by its molecular formula C12H15ClO. 3-chloro-1-(2,3,4,5-tetramethyl-phenyl)-propan-1-one features a chlorinated propanone structure with a tetramethylphenyl group attached to the carbonyl carbon. The tetramethylphenyl group consists of a benzene ring with four methyl groups (CH3) attached to each of the carbon atoms at positions 2, 3, 4, and 5. The presence of the chlorine atom at the 3-position of the propanone backbone and the electron-donating methyl groups on the phenyl ring contribute to the compound's unique chemical properties. This molecule is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its reactivity and structural diversity.

716-28-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 716-28-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 716-28:
(5*7)+(4*1)+(3*6)+(2*2)+(1*8)=69
69 % 10 = 9
So 716-28-9 is a valid CAS Registry Number.

, p. 69 - 80 (2007/10/03)

The one-pot syntheses of alkyl-10,11-dihydrodiindenothiophenes (3) by bromination and sulfurization of alkylindan-1-ones without substituents at C-2 (1) has been studied with 14 1 with C1-C4-rests at the benzene and or the cyclopentane ring. 9 dialkyl-3 and 3 tetraalkyl-3 are prepared in yields of 7-66percent; an octamethyl-3 is detected by tlc and ms. 2 dialkyl-3 are prepared too by an independent syntheses from dimethyl 2,5-bis(methylphenyl)thiophene-3,4-dicarboxylates (13).The mechanism of the one-pot syntheses, which gives diindeno-1,4-dithiines too,is discussed.The oxidation of 4 3 has been studied.Key words: Alkylindan-1-ones, alkyl-10,11-dihydrodiindenothiophenes, alkyldiindeno-1,4-dithiines, one-pot syntheses of anellated thiophenes, oxidation of anellated thiophenes.
