“…LFPs are now considered one of the most advanced and promising methods for criminal branch applications [60]. The experiment was done on the following surfaces, such as the Petri plate (2A and 2B), spatula (3A and 3B) and coin (4A and 4B) using the commonly = 0.98678 and also better sensitivity with LOD of catechol at 9.39 μM.…”

Herein, we have reported a red‐emitting 4‐methyl coumarin fused barbituric acid azo dye (4‐MCBA) synthesized by conventional method. Density functional theory (DFT) studies of tautomer compounds were done using (B3LYP) with a basis set of 6‐31G(d,p). NLO analysis has shown that tautomer has mean first‐order hyperpolarisabilities (β) value of 1.8188 × 10−30 esu and 1.0470 × 10−30 esu for azo and hydrazone forms, respectively, which is approximately nine and five times greater than the magnitude of urea. 4‐MCBA exhibited two absorption peaks in the range of 290–317 and 379–394 nm, and emission spectra were observed at 536 nm. CV study demonstrated that the modified 4‐MCBA/MGC electrode exhibited excellent electrochemical sensitivity towards the detection of catechol and the detection limit is 9.39 μM under optimum conditions. The 4‐MCBA employed as a fluorescent probe for the visualisation of LFPs on various surfaces exhibited Level‐I to level‐II LFPs, with low background interference.

“…17 Latent fingerprints (LFPs) visualization is very beneficial for the field of forensic science but several powders available for LFP development suffer from low sensitivity, low resolution, low stability and high toxicity. 18,19 To overcome this problem, some researchers have utilized fluorescent-based coumarin for LFP development.…”

The room temperature metal‐free cascade electrophilic addition/cyclization/oxidation reactions of (3‐phenoxyprop‐1‐yn‐1‐yl)benzenes to divergently synthesize various brominated benzopyran derivatives (3‐bromo‐2H‐chromenes, 3‐bromo‐2H‐chromen‐2‐ols and 3‐bromo coumarins) by tuning the amount of Br2 and H2O have been developed. The method exhibited high selectivity, mild reaction conditions, broad substrate scope, high efficiency, and the applicability for derivatization of the brominated products. The importance of the strategies provides a great advantage for selective synthesis of brominated benzopyran derivatives.
