Phthalate Standards

Applications A phthalate labelled metabolite with genotoxic effect. References Reyes, F., et al.: J. Clin. Endocrinol. Metab., 37, 74 (1973), Engel, S., et al.: Neurotoxicology, 30, 522 (2009),

Applications isotope labelled Dibenzyl Phthalate is an plasticizer used in toys that was found to exhibit potential estrogen agonist/ antagonist properties. References Zhang, Z.B., et al.: Toxicol. Lett., 207, 7 (2011); Mentlein, R., et al.: BIochem. Pharma., 38, 3126 (1989);

Applications Phthalic Acid-d4 Mono-tetrahydrogeranyl Ester is the isotope analog of Phthalic Acid Mono-tetrahydrogeranyl Ester. Phthalic Acid Mono-tetrahydrogeranyl Ester is used in biological studies for the determination of total phthalates in urine by isotope-dilution liquid chromatography tandem-mass spectrometry of phthalic acid in human urine after acid hydrolysis of metabolite mixture.

Stability Moisture Sensitive Applications 2-Isopropylphenyl Diphenyl Phosphate is a triaryl phosphate used as plasticizers in polyvinyl chloride (PVC) as well as a flame retardant. Studies show that Bis(2-isopropylphenyl) Phenyl Phosphate inhibits the human androgen receptor. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Duke, A.J.: Chimia, 32, 457 (1978); Honkakoski, P. et al.: Biochem. Pharmacol., 67, 97 (2004); Nobile, E.R. et al.: Bull. Environ. Contam. Toxicol., 25, 755 (1980);

Applications Labelled Benzyl Butyl Phthalate (B233555). A phthalate metabolite with genotoxic effect. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Reyes, F., et al.: J. Clin. Endocrinol. Metab., 37, 74 (1973), Engel, S., et al.: Neurotoxicology, 30, 522 (2009),

Applications 3-Oxo-12a-hydroxy-5β-cholanoic Acid is a keto bile acid derivative. References Bortolini, O. et al.: Tetra., 62, 4482 (2006); Bortolini, O. et al.: J. Org. Chem., 67, 5802 (2002);

Applications Dimethyl Terephthalate-2,3,5,6-d4 (CAS# 74079-01-9) is a useful isotopically labeled research compound.
