双酚 B 是双酚 A 的同类产品，主要用于制造酚醛树脂，并且也是一种潜在的食品污染物。 双酚 B 可用作通过使用原位衍生分散液相微萃取（DLLME）和中心切割气相色谱-质谱（GC-MS）联用法测定液体食品基质和婴儿配方粉和人尿液样品中双酚 B 的参考标准. Bisphenol B is a congener of bisphenol A, used primarily for the manufacturing of phenolic resins and is also a potent food contaminant. Bisphenol B may be used as a reference standard for the determination of bisphenol B in liquid food matrices and powdered infant formulae and human urine samplesby using dispersive liquid-liquid microextraction (DLLME) with in situ derivatization coupled with heart-cutting gas chromatography-mass spectrometry (GC-MS).
