Description
CATO supplies 1-Thia-7-azaspiro[4.4]Nonane 1,1-dioxide (CAS 1785316-17-7), a certified reference material (molecular formula C7H13NO2S, MW 175.25 g/mol) for analytical method development and quality control.
The molecular framework of 1-Thia-7-azaspiro[4.4]Nonane 1,1-dioxide (C7H13NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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), 1-Thia-7-azaspiro[4.4]Nonane 1,1-dioxide 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.
