Brief Introduction
P-Nitrophenylacetic acid is light yellow acicular crystal, soluble in hot water, ethanol and benzene, slightly soluble in cold water. It is mainly used in medicine and other organic synthesis, and can also be used in biochemical research. The product is obtained by hydrolysis of p-nitrophenylacetonitrile: p-nitrophenylacetonitrile, concentrated sulfuric acid and water are mixed, heated and refluxed for 15min. Then the reactant is poured into ice water, crystallized, filtered, the filter cake is washed with ice water, and recrystallized with water to obtain p-Nitrophenylacetic acid. The yield is over 92%.

2-(3,4-Dihydroxyphenyl)-3,5,7-Trihydroxy-4H-Chromen-4-One; Meletin; Quercitin; 3,3',4',5,7-Pentahydroxyflavone; Kvercetin
Brief Introduction
Quercetin is a flavonoid found in many foods and herbs and is a regular component of a normal diet. Extracts of quercetin have been used to treat or prevent diverse conditions including cardiovascular disease, hypercholesterolemia, rheumatic diseases, infections and cancer but have not been shown to be effective in clinical trials for any medical condition.
Quercetin is a natural flavonoid, which widely exists in Sophora japonica. It mainly comes from enzymatic hydrolysis of rutin and is yellow needle like crystal. It is widely used in many fields such as food, medicine, health products and so on.

Brief Introduction
3 - (2-helix adamantane) - 4-methoxy-4 - (3-phosphoxyyl) - phenyl-1,2-dioxane, abbreviated as amppd, is a chemiluminescent reagent. Amppd and luminol, as we are familiar with, are oxidation reduction luminescent reagents. However, amppd is an ultra-high sensitivity detection reagent for phosphatase, which is different from luminol, which is mainly used in blood detection.

Aceneuramic acid; N-Acetyl-D-Neuraminic acid; NANA; 5-Acetamido-3,5-Dideoxy-D-Glycero-D-Galactononulosonic acid; Sialic acid; NANA TYPE IV-S; Lactaminic acid; NAN; NANA TYPE VI; Sialomucin; NEU5AC
Brief Introduction
N-acetylneuraminic acid is the most widely distributed in nature, mainly composed of glycoprotein, glycolipid or bacterial capsule substance in animal cell membrane or secretion liquid. Sialic acid is a carbohydrate widely existing in nature, and also a basic component of many glycoproteins, glycopeptides and glycolipids. It has a wide range of biological functions, such as the regulation of half-life of blood protein, neutralization of various toxins, cell adhesion, immune antigen antibody reaction and protection of cell dissolution. The biochemical derivatives of sialic acid are also commonly used in the synthesis of drugs.
