4-(4-tert-Butylphenyl)-2-(1-methyl-1H-indol-3-yl)-4-oxobutanoic acid CAS 937604-78-9 chemical structure

Description

CATO supplies 4-(4-tert-Butylphenyl)-2-(1-methyl-1H-indol-3-yl)-4-oxobutanoic acid (CAS 937604-78-9), a certified reference material (molecular formula C23H25NO3, MW 363.45 g/mol) for analytical method development and quality control.

Structurally, 4-(4-tert-Butylphenyl)-2-(1-methyl-1H-indol-3-yl)-4-oxobutanoic acid (C23H25NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 363.45 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
