Fluorouracil Impurity 19 Hydrate (Mixture of Diastereomers) CAS 1210289-53-4

Description

The occurrence of Fluorouracil Impurity 19 Hydrate (Mixture of Diastereomers) is closely related to a carbohydrate-derived structure, an amide group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Fluorouracil Impurity 19 Hydrate (Mixture of Diastereomers) (CAS 1210289-53-4) is a certified pharmaceutical impurity reference standard with the molecular formula C4H5FN2O3H2O and a molecular weight of 166.11 g/mol.

Fluorouracil Impurity 19 Hydrate (Mixture of Diastereomers) (C4H5FN2O3H2O) contains a carbohydrate-derived structure, an amide group, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Fluorouracil Impurity 19 Hydrate (Mixture of Diastereomers) 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.
