Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 252.27 g/mol gives Methyl aminolevulinate EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methyl aminolevulinate EP Impurity C (CAS 77479-01-7) is a certified pharmaceutical impurity reference standard with the molecular formula C12H16N2O4 and a molecular weight of 252.27 g/mol.
Methyl aminolevulinate EP Impurity C (C12H16N2O4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
