Description

Compared with other compounds in its class, the molecular weight of 303.42 g/mol gives Methyl 2-amino-4-(4-sec-butylphenyl)-5-methylthiophene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 2-amino-4-(4-sec-butylphenyl)-5-methylthiophene-3-carboxylate (CAS 350992-17-5) is a high-purity analytical reference standard with the molecular formula C17H21NO2S and a molecular weight of 303.42 g/mol.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 2-amino-4-(4-sec-butylphenyl)-5-methylthiophene-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.42 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.

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.
