Détails Produit
Product description: Chemical. CAS: 4775-80-8. Formula: C11H13NO3S. MW: 239.29. Synthetic. S-Phenylmercapturic acid (S-PMA) is an important metabolite of benzene used as a biomarker for benzene exposure in humans. In industrial workers, urinary concentrations of up to 543 µg/g creatinine have been detected. In a study of benzene exposure through tobacco smoke inhalation in humans, smokers had a urinary concentration of 9.1 µg S-PMA/g creatinine compared with 4.8 µg S-PMA/g creatinine in non-smokers. S-PMA can be sensitively and reliably determined using capillary gas chromatographic/mass spectrometric method. Due to its sensitivity the method is suitable not only for determining concentrations relevant to occupational medicine, but also those which occur in the ecological range. Compound can be used as analytical reference material.
