506-58-1 Usage
Applications
Ethylammonium iodide (EAI), like methylammonium iodide, is a precursor used for high-efficiency pervoskite solar cells and LEDs.
(CH3CH2NH3)PbI3 has valence band position at 5.6?eV with an optical band-gap of ca.2.2?eV [2]. In comparison, (CH3NH3)PbI3 has a valence band position at 5.4 eV with an optical band-gap of 1.5 eV. The difference is due to the larger cation effect of (CH3CH2NH3)PbI3, resulting in less conjugation to the lead iodide to widen the band-gap of the perovskite structure.
Description
Ethylammonium iodide (EAI), like methylammonium iodide, is a precursor used for high-efficiency pervoskite solar cells and LEDs.
Uses
The iodide and bromide based alkylated halides find applications as precursors for fabrication of perovskites for photovoltaic applications.
Check Digit Verification of cas no
The CAS Registry Mumber 506-58-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 506-58:
(5*5)+(4*0)+(3*6)+(2*5)+(1*8)=61
61 % 10 = 1
So 506-58-1 is a valid CAS Registry Number.

Microwave-assisted synthesis of primary amine HX salts from halides and 7 M ammonia in methanol

The atom economical synthesis of hydrogen halide salts of primary amines, directly from the corresponding halides, avoids the production of significant amounts of secondary amine side products, and requires only evaporation of the solvent to access the products in yields generally greater than 90%. The procedure uses microwave irradiation in 7 M ammonia in methanol (Aldrich) at 130°C from 0.5 to 2.5h and works on a variety of alkyl halides, as well as mesylates and tosylates. Benzylamines are obtained from benzyl halides without significant amounts of the secondary amine side products that result without microwave heating. Direct isolation of even highly volatile primary amines as their hydrogen halide salts makes the method ideal for use in parallel synthesis.
