Preparation
4-Iodoaniline is obtained by the reaction of aniline and iodine in the presence of sodium bicarbonate. Add aniline and sodium bicarbonate to water and slowly add crushed iodine in stages with vigorous stirring. If the reaction solution is yellow, add a little sodium bisulfite to make it discolor, then filter and get the crude product. Then the product is recrystallized by ethanol to obtain 4-Iodoaniline.
Purification Methods
Crystallise it from pet ether (b 60-80o) by refluxing, then cool it in an ice-salt bath freezing mixture. Dry it in air. Alternatively, crystallise it from EtOH and dry it in vacuo for 6hours at 40o [Edidin et al. J Am Chem Soc 109 3945 1987]. The N-acetyl derivative has m 184o (from MeOH). [Beilstein 12 IV 1544.]
Check Digit Verification of cas no
The CAS Registry Mumber 540-37-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 540-37:
(5*5)+(4*4)+(3*0)+(2*3)+(1*7)=54
54 % 10 = 4
So 540-37-4 is a valid CAS Registry Number.

An efficient and recyclable Pd nano-catalyst was developed via immobilization of Pd nanoparticles on polyimide linked covalent organic frameworks (PCOFs) that was facilely prepared through condensation of melamine and 3,3′,4,4′-biphenyltetracarboxylic dianhydride. The Pd nanoparticles (Pd NPs) catalyst was thoroughly characterized by FT-IR, XRD, SEM, TEM. Furthermore, the catalytic activity of Pd NPs catalyst was evaluated by Suzuki–Miyaura coupling reaction and nitroarene reduction in water, respectively. The excellent yields of corresponding products revealing revealed that the Pd NPs catalyst could be applied as an efficient and reusable heterogeneous catalyst for above two reactions.
