Chemical Structure
Description
Structurally, 2-Chloro-N-cyclohexyl-N-(tetrahydro-1,1-dioxido-3-thienyl)acetamide (C12H20ClNO3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 293.81 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Chloro-N-cyclohexyl-N-(tetrahydro-1,1-dioxido-3-thienyl)acetamide (CAS 5553-25-3), molecular formula C12H20ClNO3S and molecular weight 293.81 g/mol, is a CATO reference standard with documented purity and traceability.
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-Chloro-N-cyclohexyl-N-(tetrahydro-1,1-dioxido-3-thienyl)acetamide 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.
