Chemical Structure

Ono-ae 1-329 CAS 253350-43-5 chemical structure

Description

CATO supplies Ono-ae 1-329 (CAS 253350-43-5), a certified reference material (molecular formula C22H30O6S2, MW 454.60 g/mol) for analytical method development and quality control.

Ono-ae 1-329 (C22H30O6S2) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures Ono-ae 1-329 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.
