4 toxicological data are used as organic synthesis of esterifying agents, and many aspects such as photographic drugs, medicine, printing and dyeing mordant, buffer, chemical reagents, meat anticorrosion, pigment, tanning and so on. It can be used to produce various chemical products, such as furan acrylic acid, acetic ester and chloroacetic acid. As a buffer for seasoning, the product can alleviate bad smell and prevent discoloration, and has certain anti mildew effect. It can also be used as an acidifying agent for sauce, sauerkraut, mayonnaise, fish cake, sausage, bread, sticky cake and so on. It is mixed with methyl cellulose and phosphate to improve the preservation of sausage, bread and sticky cake.

It can be used as common analytical reagent, mordant, buffer, and can also be u

4 毒理学数据用作有机合成的酯化剂以及摄影药品、医药、印染媒染剂、缓冲剂、化学试剂、肉类防腐、颜料、鞣革等许多方面。可用于制取各种化工产品，如、醋酸酯酸等。该品作为调味料的缓冲剂，可缓和不良气味并防止变色，具有一定的防霉作用。亦可用作调味酱、酸菜、蛋黄酱、鱼糕、香肠、面包、粘糕等的酸味剂。纤维素、磷酸盐等混合，用于提高香肠、面包、粘糕等的保存性。

用作普通分析试剂、媒染剂、缓冲剂，还可用于染料合成及影片冲洗。用于医药、印染及有机合成用作媒染剂和缓冲剂，也用于染料和制药工业用于印染、医药、摄影等，亦用作酯化剂、防腐剂。
