Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Oxo-2,3,5,9b-tetrahydro-thiazolo-[2,3-a]isoindole-3-carboxylic acid (CAS 118726-68-4), a certified reference material (molecular formula C11H9NO3S, MW 235.26 g/mol) for analytical method development and quality control.
The molecular framework of 5-Oxo-2,3,5,9b-tetrahydro-thiazolo-[2,3-a]isoindole-3-carboxylic acid (C11H9NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 5-Oxo-2,3,5,9b-tetrahydro-thiazolo-[2,3-a]isoindole-3-carboxylic acid 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.
