5-Chlormethyl-novovanillin is a chemical compound with the molecular formula C14H11ClO4. It is a derivative of novovanillin, a vanillin analog, where a chlorine atom is attached to the methyl group. 5-Chlormethyl-novovanillin is primarily used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of certain antibiotics and antifungal agents. Due to its reactivity, it is essential to handle 5-chloromethyl-novovanillin with care, following proper safety protocols to minimize potential health and environmental risks.

2973-71-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2973-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2973-71:
(6*2)+(5*9)+(4*7)+(3*3)+(2*7)+(1*1)=109
109 % 10 = 9
So 2973-71-9 is a valid CAS Registry Number.

Novel high throughput mixed matrix membranes embracing poly ionic liquid-grafted biopolymer: Fabrication, characterization, permeation and antifouling performance

Elshaarawy, Reda F.M.,Dechnik, Janina,Hassan, Hassan M.A.,Dietrich, Dennis,Betiha, Mohamed A.,Schmidt, Stephan,Janiak, Christoph

, p. 484 - 494 (2018)

We report a simple and effective protocol for preparation of a poly-ionic liquid (PIL)-grafted chitosan Schiff base (PILCSB) and titanium oxide nanoparticles (TNPs) for application as an antibiofouling nanocomposite in the fabrication of new polysulfone (PSU) ultrafiltration mixed matrix membranes (MMMs). The effect new additive (PILCSB@TNPs) on the porosity texture, pure water flux (PWF) and antibiofouling profile for modified MMMs was investigated. Interestingly, the surface hydrophilicity of these MMMs was remarkably enhanced in comparison to the neat PSU membrane (M0) as revealed from wettability and water contact- angle results (wettability/water contact angle = 29.18%/93.48° and 83.46%/57.35° for M0 and MMM6, respectively).
