2,3,4,4-Tetrachloro-3-(dichloromethyl)butanoic Acid Methyl Ester CAS 97055-35-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3,4,4-Tetrachloro-3-(dichloromethyl)butanoic Acid Methyl Ester.

2,3,4,4-Tetrachloro-3-(dichloromethyl)butanoic Acid Methyl Ester (CAS 97055-35-1), molecular formula C6H6Cl6O2 and molecular weight 322.83 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,3,4,4-Tetrachloro-3-(dichloromethyl)butanoic Acid Methyl Ester (C6H6Cl6O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 322.83 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.
