Chemical Structure

Gibberellin A20 CAS 19143-87-4 chemical structure

Description

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Gibberellin A20 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Gibberellin A20 (CAS 19143-87-4), a certified reference material (molecular formula C19H21O5, MW 329.37 g/mol) for analytical method development and quality control.

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.

As a certified reference material (CRM), Gibberellin A20 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
