Chemical Structure
Description
CATO supplies (S)-5-(1H-Indol-3-yl)-2-(3-methylpentyl)oxazole-4-carboxylic acid (CAS 213385-69-4), a certified reference material (molecular formula C18H20N2O3, MW 312.36 g/mol) for analytical method development and quality control.
The molecular framework of (S)-5-(1H-Indol-3-yl)-2-(3-methylpentyl)oxazole-4-carboxylic acid (C18H20N2O3) is characterized by a steroid core, an amide group, 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.
CATO manufactures (S)-5-(1H-Indol-3-yl)-2-(3-methylpentyl)oxazole-4-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.
