Chemical Structure

2,2,3,3,4,4,4-Heptafluorobutyl chloroformate CAS 108156-21-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2,3,3,4,4,4-Heptafluorobutyl chloroformate.

2,2,3,3,4,4,4-Heptafluorobutyl chloroformate (CAS 108156-21-4), molecular formula C5H2ClF7O2 and molecular weight 262.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,2,3,3,4,4,4-Heptafluorobutyl chloroformate (C5H2ClF7O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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.

As a certified reference material (CRM), 2,2,3,3,4,4,4-Heptafluorobutyl chloroformate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
