Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 201.13 g/mol gives Leucronine Hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Leucronine Hydrate (CAS 138-60-3), a certified reference material (molecular formula C7H5NO5H2O, MW 201.13 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5NO5H2O, Leucronine Hydrate contains a carbohydrate-derived structure, an amide group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 201.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Leucronine Hydrate 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.
