Chemical Structure

Tadalafil Impurity 116 CAS 154030-29-2 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Tadalafil Impurity 116 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Tadalafil Impurity 116 (CAS 154030-29-2), molecular formula C9H8O5 and molecular weight 196.16 g/mol, is a CATO reference standard with documented purity and traceability.

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), Tadalafil Impurity 116 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.
