Chemical Structure

Preskimmianin CAS 38695-41-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Preskimmianin.

Preskimmianin (CAS 38695-41-9), molecular formula C17H21NO4 and molecular weight 303.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Preskimmianin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.35 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.

As a certified reference material (CRM), Preskimmianin 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.
