609-99-43,5-二硝基水杨酸,98%化合物描述
3,5-Dinitrosalicylic acid (DNS or DNSA, IUPAC name 2-hydroxy-3,5-dinitrobenzoic acid) is an aromatic compound that reacts with reducing sugars and other reducing molecules to form 3-amino-5-nitrosalicylic acid, which strongly absorbs light at 540 nm. It was first introduced as a method to detect reducing substances in urine and has since been widely used, for example, for quantifying carbohydrate levels in blood. It is mainly used in assay of alpha-amylase. However, enzymatic methods are usually preferred due to DNS lack of specificity.

生产方法及用途
生产方法
三、 生产方法简述: 由水杨酸硝化而得。将水杨酸加入混酸中,在15-25℃硝化。然后将硝化物慢慢倒入冰水中,得黄色固体沉淀,经过滤、水洗,即得3,5-二硝基水杨酸。
用途
四、 用途: 医药中间体以及用于酶分析中。
