Chemical Structure

Corylin CAS 53947-92-5 chemical structure

Description

CATO supplies Corylin (CAS 53947-92-5), a certified reference material (molecular formula C20H22O4, MW 326.39 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Corylin is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 326.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
