Crystal violet lactone (cas: 1552-42-7) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Application In Synthesis of Crystal violet lactone

Banned industrial dyes are composed of a large number of chems. with diverse phys. and chem. properties, making their simultaneous determination a challenging task. A one-step extraction and purification of 93 banned industrial dyes from beverage, fish and cookie sample methods was proposed by using solid supported liquid-liquid extraction (SLE). The extract was analyzed by ultrahigh-performance liquid chromatog. quadrupole orbitrap high-resolution mass spectrometry (UPLC-Q-Orbitrap-HRMS). The quant. and qual. mode adopts Q-Orbitrap-HRMS full scan MS (full scan MS1) and data-dependent MS/MS (dd-MS2) acquisition mode. The mass resolution was screened under 70,000 FWHM for full-scan MS1 and 35,000 FWHM for dd-MS2. Linearity was observed in the range of 0.01 ∼ 0.5 μg/mL and the limits of quantification were 0.04 ∼ 0.2 mg/kg for 93 dyes. The average recoveries were 70.5-105.8%, with RSD ≤ 10%. The proposed method has the ability to simultaneously screen many banned dyes in foods with high throughput, sensitivity and reliability. In the experiment, the researchers used many compounds, for example, Crystal violet lactone (cas: 1552-42-7Application In Synthesis of Crystal violet lactone).
