13354-21-7 Usage

General Description

FLUOREN-9-ONE-2,7-DISULFONYL CHLORIDE is a chemical compound with the formula C13H6Cl2O6S2. It is a highly reactive and potentially hazardous substance. It is commonly used in organic synthesis, particularly in the preparation of fluorescent dyes. The compound is known to exhibit strong sulfonating and chlorinating properties, which makes it useful in various chemical reactions, such as the introduction of sulfonic acid groups into organic molecules. However, due to its reactivity, it requires careful handling and storage to prevent accidents or unwanted chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 13354-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,3,5 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13354-21:
(7*1)+(6*3)+(5*3)+(4*5)+(3*4)+(2*2)+(1*1)=77
77 % 10 = 7
So 13354-21-7 is a valid CAS Registry Number.

Electron acceptors of the fluorene series. Part 6.1 Synthesis of 4,5-dinitro-9-X-fluorene-2,7-disulfonic acid derivatives, their charge transfer complexes with anthracene and sensitization of photoconductivity of poly-N-(2,3-epoxypropyl)carbazole

, p. 537 - 545 (2007/10/03)

Proceeding from fluorene-2,7-disulfonyl dichloride, a number of novel fluorene electron acceptors with sulfonyl substituents have been synthesized. Formation of charge transfer complexes (CTCs) of the synthesized acceptors with anthracene in dichloroethane has been studied by appearance of long-wavelength CTC bands in the visible region of electron absorption spectra. The values of equilibrium constants determined for three acceptors (i.e. 18, 22a, 22b) show that the process of CTC formation is affected both by electronic and steric factors. Sensitization of poly-N-(2,3-epoxypropyl)carbazole (PEPC) photoconductivity with compounds 18, 21a and 22a has been studied.
