Chemical Structure

Trifluoroacetic Acid CAS 76-05-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 114.02 g/mol gives Trifluoroacetic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Trifluoroacetic Acid (CAS 76-05-1) is a high-purity analytical reference standard with the molecular formula C2HF3O2 and a molecular weight of 114.02 g/mol.

The molecular framework of Trifluoroacetic Acid (C2HF3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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), Trifluoroacetic Acid 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.
