The invention relates to daily chemical field and medicinal industry, and specifically relates to 6-aminolactose, preparation and application thereof. 6-aminolactose is shown as a formula (1). The preparation of the 6-aminolactose comprises : reacting modified lactose with sodium azide at 70-80 DEG C for 16-24 h, and purifying to obtain 6-azido-2, 3, 4-acetyllactose, wherein the molar amount of sodium azide is 2-3 times of that of lactose; reducing 6-azido-2, 3, 4-acetyllactose by employing triphenyl phosphine to obtain 6-amino-2, 3, 4-acetyllactose, wherein the molar ratio of triphenyl phosphine to lactose is 4 : 1; and performing hydrazinolysis or hydrolysis reaction to obtain 6-aminolactose. The synthetic steps are simple, the preparation method is easy to popularize, and demanded equipment and raw materials are easily available. 6-aminolactose obtained by employing the effective synthetic means is easy to purify because acetyl is used for protecting the product. The synthetic steps are simple, the preparation method is easy to popularize, and demanded equipment and raw materials are easily available. The obtained product is widely applicable to fields such as biology, medicine, foodstuff, chemical engineering and the like. The formula (1) is shown in the specification.
