Chemical Structure
Description
The occurrence of 5-(Trifluoromethyl)oxazolidin-2-one is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(Trifluoromethyl)oxazolidin-2-one (CAS 98887-20-8), molecular formula C4H4F3NO2 and molecular weight 155.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 5-(Trifluoromethyl)oxazolidin-2-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.08 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.
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), 5-(Trifluoromethyl)oxazolidin-2-one 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.
