Chemical Structure

Trichloromethyl Chloroformate CAS 503-38-8 chemical structure

Description

Trichloromethyl Chloroformate (CAS 503-38-8), molecular formula C2Cl4O2 and molecular weight 197.83 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Trichloromethyl Chloroformate (C2Cl4O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
