Description
As a certified reference material (CRM), 5-(METHYLTHIO)-2,3-DIHYDRO-1H-INDEN-1-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.
CATO supplies 5-(METHYLTHIO)-2,3-DIHYDRO-1H-INDEN-1-ONE (CAS 218452-81-4), a certified reference material (molecular formula C10H10OS, MW 178.25 g/mol) for analytical method development and quality control.
Structurally, 5-(METHYLTHIO)-2,3-DIHYDRO-1H-INDEN-1-ONE (C10H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 178.25 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
