Chemical Structure
Description
2,6-Dimethyl-3-(2-thiomethylphenyl)propiophenone (CAS 898754-81-9), molecular formula C18H20OS and molecular weight 284.42 g/mol, is a CATO reference standard with documented purity and traceability.
2,6-Dimethyl-3-(2-thiomethylphenyl)propiophenone (C18H20OS) contains a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2,6-Dimethyl-3-(2-thiomethylphenyl)propiophenone 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.
