Chemical Structure
Description
The occurrence of 3-[3-Methyl-4-(propan-2-yl)phenoxy]propane-1-sulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-[3-Methyl-4-(propan-2-yl)phenoxy]propane-1-sulfonyl chloride (CAS 1018549-08-0) is a high-purity analytical reference standard with the molecular formula C13H19ClO3S and a molecular weight of 290.81 g/mol.
3-[3-Methyl-4-(propan-2-yl)phenoxy]propane-1-sulfonyl chloride (C13H19ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 3-[3-Methyl-4-(propan-2-yl)phenoxy]propane-1-sulfonyl chloride 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.
