Chemical Structure
Description
5,6-Dihydro-4H-pyrrolo[3,4-d]thiazole Hydrobromide (CAS 365996-65-2) is a high-purity analytical reference standard with the molecular formula C5H6N2SHBr and a molecular weight of 207.09 g/mol.
5,6-Dihydro-4H-pyrrolo[3,4-d]thiazole Hydrobromide (C5H6N2SHBr) contains a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 5,6-Dihydro-4H-pyrrolo[3,4-d]thiazole Hydrobromide 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.
