Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyl-5-tosyl-5,6-dihydro-4H-pyrrolo[3,4-d]thiazole.
2-Methyl-5-tosyl-5,6-dihydro-4H-pyrrolo[3,4-d]thiazole (CAS 170456-89-0), molecular formula C13H14N2O2S2 and molecular weight 294.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-Methyl-5-tosyl-5,6-dihydro-4H-pyrrolo[3,4-d]thiazole (C13H14N2O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 294.39 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2-Methyl-5-tosyl-5,6-dihydro-4H-pyrrolo[3,4-d]thiazole 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.
