Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3R)-1,7-dithia-4-azaspiro[4.4]Nonane-3-carboxylic acid (CAS 958965-74-7) is a high-purity analytical reference standard with the molecular formula C7H11NO2S2 and a molecular weight of 205.30 g/mol.
The molecular framework of (3R)-1,7-dithia-4-azaspiro[4.4]Nonane-3-carboxylic acid (C7H11NO2S2) 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. 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).
As a certified reference material (CRM), (3R)-1,7-dithia-4-azaspiro[4.4]Nonane-3-carboxylic acid 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.
