Chemical Structure
Description
CATO supplies 3-Methylthiazolo[5,4-d]isoxazol-5-amine (CAS 1706464-22-3), a certified reference material (molecular formula C5H5N3OS, MW 155.18 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methylthiazolo[5,4-d]isoxazol-5-amine (C5H5N3OS) is characterized by 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. 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.
CATO manufactures 3-Methylthiazolo[5,4-d]isoxazol-5-amine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
