n-(4-Tert-butylphenyl)-2-chloropropanamide CAS 731012-01-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n-(4-Tert-butylphenyl)-2-chloropropanamide.

n-(4-Tert-butylphenyl)-2-chloropropanamide (CAS 731012-01-4) is a high-purity analytical reference standard with the molecular formula C13H18ClNO and a molecular weight of 239.74 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, n-(4-Tert-butylphenyl)-2-chloropropanamide is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 239.74 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.
