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 3-Trifluoromethanesulfonylpropanoic acid.
3-Trifluoromethanesulfonylpropanoic acid (CAS 1087784-56-2), molecular formula C4H5F3O4S and molecular weight 206.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Trifluoromethanesulfonylpropanoic acid (C4H5F3O4S) is characterized by a carbohydrate-derived structure, a sulfone group, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Trifluoromethanesulfonylpropanoic 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.
