Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-2-(4-pyridinyl)-1,3-thiazol-4-ol.
5-Methyl-2-(4-pyridinyl)-1,3-thiazol-4-ol (CAS 70547-50-1), molecular formula C9H8N2OS and molecular weight 192.24 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Methyl-2-(4-pyridinyl)-1,3-thiazol-4-ol (C9H8N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 5-Methyl-2-(4-pyridinyl)-1,3-thiazol-4-ol 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.
