Description
Alanyl Glutamine Impurity 22 TFA Salt (CAS 1115-78-2) is a certified pharmaceutical impurity reference standard with the molecular formula C6H12N2O3C2HF3O2 and a molecular weight of 274.19 g/mol.
Based on its molecular formula C6H12N2O3C2HF3O2, Alanyl Glutamine Impurity 22 TFA Salt contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 274.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Alanyl Glutamine Impurity 22 TFA Salt under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
