2,2,2-Trichloro-1-[4-(2,3-dichlorobenzoyl)-1H-pyrrol-2-yl]ethan-1-one CAS 338753-05-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,2-Trichloro-1-[4-(2,3-dichlorobenzoyl)-1H-pyrrol-2-yl]ethan-1-one.

2,2,2-Trichloro-1-[4-(2,3-dichlorobenzoyl)-1H-pyrrol-2-yl]ethan-1-one (CAS 338753-05-2) is a high-purity analytical reference standard with the molecular formula C13H6Cl5NO2 and a molecular weight of 385.46 g/mol.

Structurally, 2,2,2-Trichloro-1-[4-(2,3-dichlorobenzoyl)-1H-pyrrol-2-yl]ethan-1-one (C13H6Cl5NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 385.46 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
