Chemical Structure
Description
The occurrence of 4,4-Dimethyl-2-(2-((3-(trimethylsilyl)propyl)thio)ethyl)oxazol-5(4H)-one is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,4-Dimethyl-2-(2-((3-(trimethylsilyl)propyl)thio)ethyl)oxazol-5(4H)-one (CAS 91754-73-3), a certified reference material (molecular formula C13H25NO2SSi, MW 287.49 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 4,4-Dimethyl-2-(2-((3-(trimethylsilyl)propyl)thio)ethyl)oxazol-5(4H)-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4,4-Dimethyl-2-(2-((3-(trimethylsilyl)propyl)thio)ethyl)oxazol-5(4H)-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.
