Description

Compared with other compounds in its class, the molecular weight of 311.33 g/mol gives 12-Acetyl-6a,6b,10,11,11a,12-hexahydro-8,11-epoxyoxepino[4',5':3,4]pyrrolo[1,2-a]quinolin-7(8H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 12-Acetyl-6a,6b,10,11,11a,12-hexahydro-8,11-epoxyoxepino[4',5':3,4]pyrrolo[1,2-a]quinolin-7(8H)-one (CAS 281676-67-3), a certified reference material (molecular formula C18H17NO4, MW 311.33 g/mol) for analytical method development and quality control.

The molecular framework of 12-Acetyl-6a,6b,10,11,11a,12-hexahydro-8,11-epoxyoxepino[4',5':3,4]pyrrolo[1,2-a]quinolin-7(8H)-one (C18H17NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures 12-Acetyl-6a,6b,10,11,11a,12-hexahydro-8,11-epoxyoxepino[4',5':3,4]pyrrolo[1,2-a]quinolin-7(8H)-one 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.
