Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Hexahydro-2H-[1,2,5]thiadiazolo[2,3-a]pyrazine 1,1-dioxide hydrochloride.
Hexahydro-2H-[1,2,5]thiadiazolo[2,3-a]pyrazine 1,1-dioxide hydrochloride (CAS 2137989-56-9) is a high-purity analytical reference standard with the molecular formula C5H11N3O2SHCl and a molecular weight of 213.68 g/mol.
The molecular framework of Hexahydro-2H-[1,2,5]thiadiazolo[2,3-a]pyrazine 1,1-dioxide hydrochloride (C5H11N3O2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Hexahydro-2H-[1,2,5]thiadiazolo[2,3-a]pyrazine 1,1-dioxide hydrochloride 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.
