Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Difluoro-4-(sulfinylamino)benzene.
1,2-Difluoro-4-(sulfinylamino)benzene (CAS 530102-74-0), molecular formula C6H3F2NOS and molecular weight 175.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Difluoro-4-(sulfinylamino)benzene (C6H3F2NOS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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), 1,2-Difluoro-4-(sulfinylamino)benzene 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.
