Chemical Structure

O-Desmethyl staurosporin, >98% CAS 161743-35-7 chemical structure

Description

The occurrence of O-Desmethyl staurosporin, >98% 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.

O-Desmethyl staurosporin, >98% (CAS 161743-35-7), molecular formula C27H24N4O3 and molecular weight 452.50 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, O-Desmethyl staurosporin, >98% (C27H24N4O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 452.50 g/mol, it falls into the moderately-high-molecular-weight range. 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), O-Desmethyl staurosporin, >98% 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.
