Description
CATO manufactures 11-cis-3,4-Didehydro Retinal 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.
CATO supplies 11-cis-3,4-Didehydro Retinal (CAS 41470-05-7), a certified reference material (molecular formula C20H26O, MW 282.42 g/mol) for analytical method development and quality control.
The molecular framework of 11-cis-3,4-Didehydro Retinal (C20H26O) is characterized by a steroid core, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
