Chemical Structure

Grayanotoxin III CAS 4678-45-9 chemical structure

Description

As a certified reference material (CRM), Grayanotoxin III 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.

CATO supplies Grayanotoxin III (CAS 4678-45-9), a certified reference material (molecular formula C20H34O6, MW 370.48 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, Grayanotoxin III is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 370.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
