Methyl 4-acetamido-3-nitrobenzoate CAS 6313-39-9

Description

Compared with other compounds in its class, the molecular weight of 404.47 g/mol gives Methyl 4-acetamido-3-nitrobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 4-acetamido-3-nitrobenzoate (CAS 6313-39-9), molecular formula C11H18O4P2S4 and molecular weight 404.47 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 4-acetamido-3-nitrobenzoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
