Description
As a certified reference material (CRM), Methyl 2,6-Dichloro-4-(methylthio)benzoate 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.
Methyl 2,6-Dichloro-4-(methylthio)benzoate (CAS 1823359-63-2), molecular formula C9H8Cl2O2S and molecular weight 251.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H8Cl2O2S, Methyl 2,6-Dichloro-4-(methylthio)benzoate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
