Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 270.25 g/mol gives Sepiapterin Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sepiapterin Impurity 13 (CAS CATO-C4X-276613) is a certified pharmaceutical impurity reference standard with the molecular formula C9H14N6O4 and a molecular weight of 270.25 g/mol.
Sepiapterin Impurity 13 (C9H14N6O4) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), Sepiapterin Impurity 13 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
