Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (7aR,8R,8aS,11S,11aR)-8-Ethyl-11-methyl-2-((2S,4S)-4-methyl-5-oxotetrahydrofuran-2-yl)-5,6,7,7a,8,8a,11,11a-octahydroazepino[3,2,1-hi]furo[3,2-e]indol-10(4H)-one.

(7aR,8R,8aS,11S,11aR)-8-Ethyl-11-methyl-2-((2S,4S)-4-methyl-5-oxotetrahydrofuran-2-yl)-5,6,7,7a,8,8a,11,11a-octahydroazepino[3,2,1-hi]furo[3,2-e]indol-10(4H)-one (CAS 106861-40-9), molecular formula C22H29NO4 and molecular weight 371.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (7aR,8R,8aS,11S,11aR)-8-Ethyl-11-methyl-2-((2S,4S)-4-methyl-5-oxotetrahydrofuran-2-yl)-5,6,7,7a,8,8a,11,11a-octahydroazepino[3,2,1-hi]furo[3,2-e]indol-10(4H)-one (C22H29NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 371.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.

As a certified reference material (CRM), (7aR,8R,8aS,11S,11aR)-8-Ethyl-11-methyl-2-((2S,4S)-4-methyl-5-oxotetrahydrofuran-2-yl)-5,6,7,7a,8,8a,11,11a-octahydroazepino[3,2,1-hi]furo[3,2-e]indol-10(4H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
