2-Tert-butyl-4-[(3,4,5-trimethoxyphenyl)methylidene]-1,2,3,4-tetrahydroacridine-9-carboxylic acid CAS 519150-66-4 chemical structure

Description

As a certified reference material (CRM), 2-Tert-butyl-4-[(3,4,5-trimethoxyphenyl)methylidene]-1,2,3,4-tetrahydroacridine-9-carboxylic acid 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.

2-Tert-butyl-4-[(3,4,5-trimethoxyphenyl)methylidene]-1,2,3,4-tetrahydroacridine-9-carboxylic acid (CAS 519150-66-4) is a high-purity analytical reference standard with the molecular formula C28H31NO5 and a molecular weight of 461.55 g/mol.

The molecular framework of 2-Tert-butyl-4-[(3,4,5-trimethoxyphenyl)methylidene]-1,2,3,4-tetrahydroacridine-9-carboxylic acid (C28H31NO5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
