Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(S)-5-(2-Chloroacetyl)-3,4-dihydroxyfuran-2(5H)-one (CAS 120912-36-9), molecular formula C6H5ClO5 and molecular weight 192.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, chlorine substitution, (S)-5-(2-Chloroacetyl)-3,4-dihydroxyfuran-2(5H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (S)-5-(2-Chloroacetyl)-3,4-dihydroxyfuran-2(5H)-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.
