(4-Methylphenyl)methyl 2-(4-ethylphenyl)-1-oxo-1,2-dihydroisoquinoline-4-carboxylate CAS 1708401-75-5

Description

As a certified reference material (CRM), (4-Methylphenyl)methyl 2-(4-ethylphenyl)-1-oxo-1,2-dihydroisoquinoline-4-carboxylate 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.

(4-Methylphenyl)methyl 2-(4-ethylphenyl)-1-oxo-1,2-dihydroisoquinoline-4-carboxylate (CAS 1708401-75-5) is a high-purity analytical reference standard with the molecular formula C26H23NO3 and a molecular weight of 397.47 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (4-Methylphenyl)methyl 2-(4-ethylphenyl)-1-oxo-1,2-dihydroisoquinoline-4-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
