[(3Z)-1-[(4-Methylphenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino pentanoate CAS 303149-55-5

Description

As a certified reference material (CRM), [(3Z)-1-[(4-Methylphenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino pentanoate 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.

[(3Z)-1-[(4-Methylphenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino pentanoate (CAS 303149-55-5) is a high-purity analytical reference standard with the molecular formula C21H22N2O3 and a molecular weight of 350.41 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, [(3Z)-1-[(4-Methylphenyl)methyl]-2-oxo-2,3-dihydro-1H-indol-3-ylidene]amino pentanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
