Stable isotope labeled compounds are widely used analytical reagents in food testing, environmental monitoring, analytical testing, clinical diagnostics, life sciences, and pharmaceutical research. Common stable isotopes such as deuterium, carbon-13, nitrogen-15, oxygen-18 labeled compounds, have same or very similar physical and chemical properties, definite difference of molecular weight, and greatly improved Mass detection sensitivity in comparison with unlabeled compounds, therefore are widely use as internal standards in the research and application of spectroscopy, especially mass spectrometry and LC-MS and GC-MS analysis. Stable isotope labeled products such as deuterated carbaryl, trichlorfon and dichlorvos, deuterated and carbon-13-labeled HCH facilitate the rapid detection of trace pesticide residues in fruits and vegetables; Isotopically labeled Sudan Red, Crystal Violet, Melamine, etc. used for isotope dilution detection of illegal food additives; Deuterated chlorpyrifos and chlorpromazine used for internal standard effectively reduced the influence of the sample matrix; Deuterated β-adrenergic receptors and sulfonamides, nitrogen-15 labeled nitrofuran metabolites are used for the detection of trace veterinary drug residues; Isotope labeled amino acids are important reagents for the neonatal cord blood screening ; Isotope labeled hormones, vitamins, glucoses used for clinical diagnosis. In addition, a large number of stable isotope labeled reagents have been widely used in environmental monitoring, medical research, agriculture, forestry, ecology, soil, geology, and hydrology.
Alta Scientific Co., Ltd. has many years of experiences in the research and production of organic standards and stable isotope labeling technology. Based on the rapid growth and long-term demand for stable isotope labeled products, Alta Scientific has developed variety of deuterated, carbon-13, and nitrogen-15 labeled pesticides, veterinary drugs, medicine, food additives, and environmental standards to full fill the customer’s needs.
