2. Used in photography. This aromatic compound is used by chemists to identify alcohol components in esters and in the fluorometric analysis of creatinine.

Purification Methods

Crystallise it from CCl4 or pet ether (b 40-60o). It reacts readily with H2O and should be kept in sealed ampoules. [Beilstein 9 IV 1350.]

Check Digit Verification of cas no

The CAS Registry Mumber 99-33-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99-33:
(4*9)+(3*9)+(2*3)+(1*3)=72
72 % 10 = 2
So 99-33-2 is a valid CAS Registry Number.

New metal complex systems as electrode active components of ion selective electrode membranes

Nemilova, M. Yu.,Shvedene,Mikhalev,Fedyanin,Shpakovsky

, p. 736 - 744 (2017)

New donor-acceptor 3d-transition metal complexes were synthesized and the cobalt and nickel complexes were studied by X-ray diffraction; CIF files CCDC no. 1516693 (III(Ni)) and 1516694 (III(Co)). The crystal structure details of the reactants were discussed. The proposed compounds were tested as the active components of ion selective electrode membranes for determination of thiocyanate ions. The selectivity of the SCN-SE with metal complex-based membranes depends on the ligand structure and the central metal ion type. The proposed electrode is suitable for determination of thiocyanate ions in the presence of sulfate, chloride, nitrate, nitrite, bromide, and iodide ions.

Lead derivatization of ethyl 6-bromo-2-((dimethylamino)methyl)-5-hydroxy-1-phenyl-1H-indole-3-carboxylate and 5-bromo-2-(thiophene-2-carboxamido) benzoic acid as FabG inhibitors targeting ESKAPE pathogens

Varakala, Saiprasad Dasugari,Reshma, Rudraraju Srilakshmi,Schnell, Robert,Dharmarajan, Sriram

, (2021/11/26)

Our previous studies on FabG have identified two compounds 5-bromo-2-(thiophene-2-carboxamido) benzoic acid (A) and ethyl 6-bromo-2-((dimethylamino)methyl)-5-hydroxy-1-phenyl-1H-indole-3-carboxylate(B) as best hits with allosteric mode of inhibition. FabG is an integral part of bacterial fatty acid biosynthetic system FAS II shown to be an essential gene in most ESKAPE Pathogens. The current work is focussed on lead expansion of these two hit molecules which ended up with forty-three analogues (twenty-nine analogues from lead compound A and fourteen compounds from lead compound B). The enzyme inhibition studies revealed that compound 15 (effective against EcFabG, AbFabG, StFabG, MtFabG1) and 19 (inhibiting EcFabG and StFabG) had potency of broad-spectrum inhibition on FabG panel.

Benzimidazole tethered thioureas as a new entry to elastase inhibition and free radical scavenging: Synthesis, molecular docking, and enzyme inhibitory kinetics

Abbas, Qamar,Ashraf, Saba,Channar, Pervaiz Ali,Hassan, Abbas,Hassan, Mubashar,Rafique, Hummera,Raza, Hussain,Rind, Mahboob Ali,Saeed, Aamer,Seo, Sung-Yum,Ujan, Rabail,Ul-Hamid, Anwar

The porcine pancreatic elastase inhibition and free-radical scavenging play a crucial role in age progression. All the series of 10 newly synthesized benzimidazole thioureas (4a-j) were assessed for elastase inhibition and radical scavenging activity to identify the suitable anti-aging ingredient for cosmetics products. The compounds 4e, 4f, 4g, and 4h showed inhibition better than the standard, while compound 4f showed the most significant elastase inhibition with the IC50 value of 1.318 ± 0.025 μM compared with oleanic acid IC50 13.451 ± 0.014 used ±1.989 and 41.563 ± 0.824, respectively, as standard. Molecular docking studies were performed and the compound 4f showed binding energy of 7.2 kcal/mol. Kinetics studies revealed inhibition of the pancreatic elastase in a competitive manner. The relative binding energy and structure activity relationship (SAR) identified compound 4f as an effective inhibitor of porcine pancreatic elastase. Compounds 4e and 4i showed remarkable free-radical scavenging activity with SC50 values of 26.421.
