8-(anilino)-1-naphthalenesulfonate (ANS) analogs and methods for their use in analyte detection assays are provided. The subject ANS analogs are characterized by having at least one non-hydrogen substituent on their phenyl moiety and producing a reaction product with 3-methyl-benzothiazolinone hydrazone hydrochloride (MBTH) or an analog thereof, e.g. MBTHSB, that exhibits reduced drift. In certain preferred embodiments, the subject ANS analogs are described by formula (I) wherein: n is 1 to 5; and X is a substituent other than H. The subject ANS analogs find use in a variety of applications, particularly in analyte detection assays, such as glucose detection assays.
本发明提供了 8-(
苯胺基)-
1-萘磺酸盐 (ANS) 类似物及其用于分析物检测测定的方法。所述 ANS 类似物的特征在于其苯基上至少有一个非氢取代基,并且与 3-甲基-
苯并噻唑啉酮腙盐酸盐(
MBTH)或其类似物(如
MBTHSB)生成的反应产物漂移减小。在某些优选的实施方案中,所述 ANS 类似物由式(I)描述,其中:n 是 1 至 5;X 是除 H 以外的取代基。
