Chemical Structure
Description
3,3'-Dithiobis[n-acetyl-valine (CAS 67809-84-1), molecular formula C14H24N2O6S2 and molecular weight 380.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,3'-Dithiobis[n-acetyl-valine (C14H24N2O6S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3,3'-Dithiobis[n-acetyl-valine 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.
