Description

4079-26-9 PD 146176 (1)Benzothiopyrano(4,3-b)indole, 6,11-dihydro- NSC 168807 PD-146176 6,11-Dihydro-5-thia-11-aza-benzo(a)fluorene (CAS 4079-26-9), molecular formula C15H25NS and molecular weight 251.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4079-26-9 PD 146176 (1)Benzothiopyrano(4,3-b)indole, 6,11-dihydro- NSC 168807 PD-146176 6,11-Dihydro-5-thia-11-aza-benzo(a)fluorene (C15H25NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 251.43 g/mol, it falls into the medium-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), 4079-26-9 PD 146176 (1)Benzothiopyrano(4,3-b)indole, 6,11-dihydro- NSC 168807 PD-146176 6,11-Dihydro-5-thia-11-aza-benzo(a)fluorene 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.
