用途?
1. 用作飼料添加劑
2. 是一種新穎的多功能飼料添加劑，能顯著促進(jìn)家畜、家禽、魚、蝦、牛羊等動(dòng)物的生長(zhǎng)，改善生產(chǎn)與繁殖性能
3.作為氫源，應(yīng)用于有機(jī)催化還原性胺化反應(yīng)以及共軛還原反應(yīng)中。
飼料添加劑：二氫吡啶是一種新型綠色多功能的飼料添加劑，具有廣泛的生物學(xué)功能，在醫(yī)學(xué)上用作心血管疾病的防治保健藥物，有治療脂肪肝、中毒性肝炎、抗衰老、防早熟等作用。進(jìn)一步科學(xué)研究發(fā)現(xiàn)，二氫吡啶具有促進(jìn)動(dòng)物生長(zhǎng)、改善皮毛質(zhì)量、提高瘦肉率、提高繁殖性能及防病抗病等功能。二氫吡啶最初由前蘇聯(lián)科學(xué)家合成并應(yīng)用，因其具有天然抗氧化劑VE的某些作用，最早在20世紀(jì)30年代，主要用作動(dòng)植物油的抗氧化劑，70年代，前蘇聯(lián)拉脫維亞專家們(ValdmanAReChemicalbooktal.1997)發(fā)現(xiàn)其具有促進(jìn)畜禽生長(zhǎng)作用以來(lái)，世界各國(guó)相繼展開了相關(guān)研究，并發(fā)現(xiàn)二氫吡啶有促進(jìn)畜禽生長(zhǎng)、改善畜禽產(chǎn)品品質(zhì)、提高畜禽繁殖性能及防病等功能。我國(guó)對(duì)二氫吡啶的研究開始于20世紀(jì)80年代初，現(xiàn)已有多個(gè)廠家批量生產(chǎn)和投入使用，取得較好的試驗(yàn)效果。二氫吡啶能抑制脂類化合物的過(guò)氧化過(guò)程，從而阻止生物膜的氧化，對(duì)體內(nèi)的組織細(xì)胞產(chǎn)生保護(hù)作用，具有天然抗氧化劑維生素E的某些功能。因而可提高牛、羊、豬、雞、鵪鶉等畜禽的日增重，尤其能提高奶牛情期受胎率、種公牛精液質(zhì)量及種肉雞的受精率，且可抑制動(dòng)物體內(nèi)脂肪形成，提高胴體瘦肉比率。

Physical and chemical properties:

Light yellow powder or needle crystal, non-toxic, tasteless, light color gradient deep, easy to oxidize, soluble in hot ethanol, slightly soluble in water.

use

1. Used as a feed additive

2. It is a novel multi-functional feed additive, which can significantly promote the growth of livestock, poultry, fish, shrimp, cattle and sheep, and improve the production and reproductive performance

3. As a hydrogen source, it is used in organic catalytic reductive amination and conjugated reduction reactions.

Feed additive: Dihydropyridine is a new kind of green multifunctional feed additive, which has a wide range of biological functions. It is used as prevention and health care drug for cardiovascular diseases in medicine, and has the functions of treating fatty liver, toxic hepatitis, anti-aging, preventing early maturity and so on. Further scientific research found that dihydropyridine has the functions of promoting animal growth, improving fur quality, increasing lean meat rate, improving reproductive performance and disease prevention and resistance. Two hydrogen pyridine synthesis and application by the former Soviet union scientists initially, because of its natural antioxidant some function of VE, the earliest in the 1930 s, mainly used as animal and plant oil antioxidants, in the 70 s, the former Soviet union Latvia experts (ValdmanAReChemicalbooktal. 1997) found that since it has the effect to promote animal growth, countries around the world have carried out related research, and found two hydrogen pyridine has functions of promoting animal growth and improving the quality of livestock and poultry products, improve livestock and poultry breeding performance and diseases, etc. The research on dihydropyridine in Our country began in the early 1980s, and now there are a number of manufacturers to produce and put into use, and good experimental results have been obtained. Dihydropyridine can inhibit the lipid peroxidation process,
