Chemical Structure

(-)-Antofine CAS 32671-82-2 chemical structure

Description

The occurrence of (-)-Antofine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(-)-Antofine (CAS 32671-82-2), molecular formula C23H25NO3 and molecular weight 363.45 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (-)-Antofine (C23H25NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 363.45 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), (-)-Antofine 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.
