Description

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.

CATO supplies (S)-(1R,2R,3R,3aS,3a1S,4R,6aR,7aS,11S,11aS,11bR)-1,2,11-Trihydroxy-3,8,11a-trimethyl-5,10-dioxo-2,3,3a,4,5,6a,7,7a,10,11,11a,11b-dodecahydro-1H-1,3a1-(epoxymethano)dibenzo[de,g]chromen-4-yl 2-hydroxy-2-methylbutanoate (CAS 1259-86-5), a certified reference material (molecular formula C25H34O10, MW 494.53 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, (S)-(1R,2R,3R,3aS,3a1S,4R,6aR,7aS,11S,11aS,11bR)-1,2,11-Trihydroxy-3,8,11a-trimethyl-5,10-dioxo-2,3,3a,4,5,6a,7,7a,10,11,11a,11b-dodecahydro-1H-1,3a1-(epoxymethano)dibenzo[de,g]chromen-4-yl 2-hydroxy-2-methylbutanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 494.53 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).

CATO manufactures (S)-(1R,2R,3R,3aS,3a1S,4R,6aR,7aS,11S,11aS,11bR)-1,2,11-Trihydroxy-3,8,11a-trimethyl-5,10-dioxo-2,3,3a,4,5,6a,7,7a,10,11,11a,11b-dodecahydro-1H-1,3a1-(epoxymethano)dibenzo[de,g]chromen-4-yl 2-hydroxy-2-methylbutanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
