Description

383-64-2 Ethylthiol trifluoroacetate S-Ethyl trifluorothioacetate Ethanethioic acid, 2,2,2-trifluoro-, S-ethyl ester Ethanethioic acid, trifluoro-, S-ethyl ester Acetic acid, trifluorothio-, S-ethyl ester AI3-52656 EINECS 206-852-1 Ethyl trifluorothiolacetate NSC 88936 Trifluoroacetonylmercaptoethanol (CAS 383-64-2), molecular formula C4H5F3OS and molecular weight 158.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 383-64-2 Ethylthiol trifluoroacetate S-Ethyl trifluorothioacetate Ethanethioic acid, 2,2,2-trifluoro-, S-ethyl ester Ethanethioic acid, trifluoro-, S-ethyl ester Acetic acid, trifluorothio-, S-ethyl ester AI3-52656 EINECS 206-852-1 Ethyl trifluorothiolacetate NSC 88936 Trifluoroacetonylmercaptoethanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.14 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), 383-64-2 Ethylthiol trifluoroacetate S-Ethyl trifluorothioacetate Ethanethioic acid, 2,2,2-trifluoro-, S-ethyl ester Ethanethioic acid, trifluoro-, S-ethyl ester Acetic acid, trifluorothio-, S-ethyl ester AI3-52656 EINECS 206-852-1 Ethyl trifluorothiolacetate NSC 88936 Trifluoroacetonylmercaptoethanol 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.
