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 E5B7C16LFK 22619-35-8 Tioclomarol Tioclomarol [INN:DCF] 3-(5-Chloro-alpha-(p-chloro-beta-hydroxyphenethyl)-2-thenyl)-4-hydroxycoumarin EINECS 245-132-1 Tioclomarolum [INN-Latin] Tioclomarolum UNII-E5B7C16LFK.
E5B7C16LFK 22619-35-8 Tioclomarol Tioclomarol [INN:DCF] 3-(5-Chloro-alpha-(p-chloro-beta-hydroxyphenethyl)-2-thenyl)-4-hydroxycoumarin EINECS 245-132-1 Tioclomarolum [INN-Latin] Tioclomarolum UNII-E5B7C16LFK (CAS 22619-35-8), molecular formula C22H16Cl2O4S and molecular weight 447.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, E5B7C16LFK 22619-35-8 Tioclomarol Tioclomarol [INN:DCF] 3-(5-Chloro-alpha-(p-chloro-beta-hydroxyphenethyl)-2-thenyl)-4-hydroxycoumarin EINECS 245-132-1 Tioclomarolum [INN-Latin] Tioclomarolum UNII-E5B7C16LFK is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 447.33 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.
