99203-66-4 CAS 99203-66-4 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 3-(3,4-Dimethoxyphenyl)-1-O-tosylpropanol 99203-66-4.

3-(3,4-Dimethoxyphenyl)-1-O-tosylpropanol 99203-66-4 (CAS 99203-66-4) is a high-purity analytical reference standard with the molecular formula C18H22O5S and a molecular weight of 350.43 g/mol.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, 3-(3,4-Dimethoxyphenyl)-1-O-tosylpropanol 99203-66-4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.43 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).

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.
