Chemical Structure
Description
3-Phenylthiazolo[5,4-d]isoxazol-5-amine (CAS 193345-25-4), molecular formula C10H7N3OS and molecular weight 217.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Phenylthiazolo[5,4-d]isoxazol-5-amine (C10H7N3OS) 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 its high hydrophobicity (logP), 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), 3-Phenylthiazolo[5,4-d]isoxazol-5-amine 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.
