Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 371.54 g/mol gives R-Arotinolol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
R-Arotinolol (CAS CATO-C4X-185481) is a high-purity analytical reference standard with the molecular formula C15H21N3O2S3 and a molecular weight of 371.54 g/mol.
Based on its molecular formula C15H21N3O2S3, R-Arotinolol contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 371.54 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), R-Arotinolol 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.
