2-Methyl-4,4,4-trifluorobutyricacid CAS 99783-23-0

Description

Compared with other compounds in its class, the molecular weight of 156.10 g/mol gives 2-Methyl-4,4,4-trifluorobutyricacid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-4,4,4-trifluorobutyricacid (CAS 99783-23-0), molecular formula C5H7F3O2 and molecular weight 156.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Methyl-4,4,4-trifluorobutyricacid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-Methyl-4,4,4-trifluorobutyricacid 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.
