(1aS,2S,3R,11bR)-1a,2,3,11b-Tetrahydrobenz[7,8]anthra[1,2-β]oxirene-2,3-diol CAS 64937-40-2

Description

The occurrence of (1aS,2S,3R,11bR)-1a,2,3,11b-Tetrahydrobenz[7,8]anthra[1,2-β]oxirene-2,3-diol is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(1aS,2S,3R,11bR)-1a,2,3,11b-Tetrahydrobenz[7,8]anthra[1,2-β]oxirene-2,3-diol (CAS 64937-40-2), molecular formula C18H14O3 and molecular weight 278.30 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1aS,2S,3R,11bR)-1a,2,3,11b-Tetrahydrobenz[7,8]anthra[1,2-β]oxirene-2,3-diol (C18H14O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

As a certified reference material (CRM), (1aS,2S,3R,11bR)-1a,2,3,11b-Tetrahydrobenz[7,8]anthra[1,2-β]oxirene-2,3-diol 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.
