Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
n'-Hydroxy-2-(5-methyl-1,3-thiazol-2-yl)ethanimidamide (CAS 855991-69-4), molecular formula C6H9N3OS and molecular weight 171.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of n'-Hydroxy-2-(5-methyl-1,3-thiazol-2-yl)ethanimidamide (C6H9N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), n'-Hydroxy-2-(5-methyl-1,3-thiazol-2-yl)ethanimidamide 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.
