3443-45-6 Usage

Chemical Properties

Pale yellow or yellow-beige crystalline powder

Uses

Different sources of media describe the Uses of 3443-45-6 differently. You can refer to the following data:
1. 1-Pyrenebutyric Acid is a fluorescent probe used to study proteins, lipids, nucleic acids and other biological systems. The fluorescence lifetime of 1-Pyrenebutyric Acid depends on local oxygen and fr ee radical concentration.
2. 1-Pyrenebutyric Acid is a fluorescent probe used to study proteins, lipids, nucleic acids and other biological systems. The fluorescence lifetime of 1-Pyrenebutyric Acid depends on local oxygen and free radical concentration.

General Description

1-Pyrenebutyric acid (PBA) is a conjugated polymer that has a large π system and a carboxylic group. It is majorly used in surface functionalization. It has a high fluorescence efficiency and stability that make it useful in optoelectronic applications.

Purification Methods

Crystallise the butyric acid from *benzene, EtOH, EtOH/water (7:3 v/v) or *C6H6/AcOH. Dry it over P2O5. [Chu & Thomas J Am Chem Soc 108 6270 1986, Beilstein 9 IV 2731.]

Check Digit Verification of cas no

The CAS Registry Mumber 3443-45-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3443-45:
(6*3)+(5*4)+(4*4)+(3*3)+(2*4)+(1*5)=76
76 % 10 = 6
So 3443-45-6 is a valid CAS Registry Number.

Synthesis of benzo[a]pyren-6-yl-substituted carboxylic acids

Dyker, Gerald,Kadzimirsz, Daniel

, p. 3167 - 3172 (2003)

The title compounds were synthesized from benzo[a]pyrene in three to four steps, depending on the chain length of the carboxylic acid. After iodination, alkanone chains were introduced by special Heck reactions. Transformation into carboxylic acids was achieved by haloform reaction and by Willgerodt-Kindler reaction.

Chromophore quench-Labeling: An approach to quantifying catalyst speciation as demonstrated for (EBI)ZrMe2/ b(C6F5)3?Catalyzed polymerization of 1?Hexene

Nelsen, D. Luke,Anding, Bernie J.,Sawicki, Julie L.,Christianson, Matthew D.,Arriola, Daniel J.,Landis, Clark R.

, p. 7398 - 7408 (2018/05/23)

Chromophore-containing quench agents 2 and 3 enable quantitative active site counting and determination of the mass distribution of active catalyst polymeryls by refractive index (RI) and UV detected gel permeation chromatography (GPC) for the polymerization of 1-hexene catalyzed by (EBI)ZrMe2/B(C6F5)3. Time evolution of catalyst speciation data and the time profiles of monomer consumption, end-group generation, and bulk molecular weight distribution data have been analyzed by kinetic modeling to determine rate constants for initiation by insertion of hexene into a Zr?Me bond (ki), propagation (kp), chain transfer to form vinylidene (k1,2) and vinylene (k2,1) end groups, and reinitiation from a Zr?H bond (kr). Unlike previous models that assumed fast catalyst reinitiation, this analysis reveals that kr is considerably slower than kp; catalyst speciation data are critical to making this distinction. This study demonstrates that chromophore quench-labeling with 2 and 3 enables rapid, quantitative analysis of detailed kinetic models for catalytic olefin polymerization reactions using GPC with UV and RI detectors.
