COA of Formula: C7H5NO4. I found the field of Chemistry very interesting. Saw the article Amine decorated polystyrene nanobeads incorporating pi-conjugated OPV chromophore for picric acid sensing in water published in 2020.0, Reprint Addresses Makkad, SK (corresponding author), Govt Autonomous NPG Coll Sci, Raipur, Madhya Pradesh, India.; Makkad, SK (corresponding author), Natl Chem Lab, CSIR, Pune, Maharashtra, India.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid.
A solution as well as solid state based sensor has been developed for selective detection of picric acid (PA) in water. Oligo (p-phenylenevinylene) (OPV) incorporated polystyrene nanobeads (PS-OPV-NH2) having an average size of 180 nm have been synthesized through miniemulsion polymerization. Amine (-NH2) functionalization was performed on the nanobead surface to enhance the efficiency of the sensor among a library of other nitro-organics and library of cations and anions.
COA of Formula: C7H5NO4. About 4-Nitrobenzoic acid, If you have any questions, you can contact Makkad, SK or concate me.
