21900-25-4 Usage

General Description

4-Bromo-3-methylbenzoyl chloride is a chemical compound with the formula C8H7BrOCl. It is a colorless to pale yellow liquid that is primarily used in the synthesis of pharmaceuticals and agrochemicals. In particular, it is a key intermediate in the production of nonsteroidal anti-inflammatory drugs (NSAIDs) such as Ibuprofen. 4-BROMO-3-METHYLBENZOYL CHLORIDE is also utilized in the preparation of various organic compounds and active pharmaceutical ingredients. It is important to handle 4-Bromo-3-methylbenzoyl chloride with caution, as it is a reactive and corrosive material that should be stored and used in a well-ventilated area with appropriate personal protective equipment.

Check Digit Verification of cas no

The CAS Registry Mumber 21900-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21900-25:
(7*2)+(6*1)+(5*9)+(4*0)+(3*0)+(2*2)+(1*5)=74
74 % 10 = 4
So 21900-25-4 is a valid CAS Registry Number.

The optimization of a series of benzimidazole-benzoxaborole hybrid molecules linked via a ketone that exhibit good activity against Onchocerca volvulus, a filarial nematode responsible for the disease onchocerciasis, also known as river blindness, is desc

Studies on phenothiazines: New microtubule-interacting compounds with phenothiazine A-ring as potent antineoplastic agents

Ghinet, Alina,Moise, Iuliana-Monica,Rigo, Beno?t,Homerin, Germain,Farce, Amaury,Dubois, Jo?lle,B?cu, Elena

, p. 2307 - 2317 (2016/04/26)

New phenothiazine derivatives 6-20 have been designed, synthesized and evaluated in vitro for their ability to inhibit tubulin polymerization and antiproliferative activity against 60 cancer cell lines, including several multi-drug resistant (MDR) tumor cell lines. The phenothiazine unit may successfully replace the classical 3,4,5-trimethoxyphenyle A ring of parent combretastatin A-4 or phenstatin, confirming previous studies. The most promising structural modulations have been realized on the B ring, the 2′-fluoro-4′-methoxy substitution in compound 6 and the 2′-trifluoromethyl-4′-methoxy substitution in compound 7 providing the best antitubulin and antitumor activity in the current study. Compounds 6-8 and 16 exhibited more important cell growth inhibition than parent phenstatin 2 on human colon Duke's type D, colorectal adenocarcinoma COLO 205 and on human kidney adenocarcinoma A498 cell lines. 10-Methylphenothiazine derivatives 19 and 20 did not show biological activity but exerted bright fluorescence and solvatochromism effects. These molecules deserve further chemical efforts in order to provide valuable tools for biophysical studies.
