In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Rapid monitoring of black tea fermentation quality based on a solution-phase sensor array combined with UV-visible spectroscopy, published in 2022-05-30, which mentions a compound: 28903-71-1, mainly applied to black tea fermentation quality UV visible spectroscopy; solution phase sensor array; Black tea; Fermentation; Nanoporphyrin; Solution-phase sensor array; UV-visible spectroscopy, Synthetic Route of C48H38CoN4O4.
Rapid monitoring of fermentation quality has been the key to realizing the intelligent processing of black tea. In our study, mixing ratios, sensing array components and reaction times were optimized before an optimal solution phase colorimetric sensor array was constructed. The characteristic spectral information of the array was obtained by UV-visible spectroscopy and subsequently combined with machine learning algorithms to construct a black tea fermentation quality evaluation model. The competitive adaptive reweighting algorithms (CARS)-support vector machine model discriminated the black tea fermentation degree with 100% accuracy. For quantification of catechins and four theaflavins (TF, TFDG, TF-3-G, and TF-3′-G), the correlation coefficients of the CARS least square support vector machine model prediction set were 0.91, 0.86, 0.76, 0.72 and 0.79, resp. The results obtained within 2 min enabled accurate monitoring of the fermentation quality of black tea, which provides a new method and idea for intelligent black tea processing.
After consulting a lot of data, we found that this compound(28903-71-1)Synthetic Route of C48H38CoN4O4 can be used in many types of reactions. And in most cases, this compound has more advantages.
