Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-{3-[(tert-Butyldimethylsilyl)oxy]cyclobutylidene}acetate.
Ethyl 2-{3-[(tert-Butyldimethylsilyl)oxy]cyclobutylidene}acetate (CAS 1638764-67-6), molecular formula C14H26O3Si and molecular weight 270.44 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H26O3Si, Ethyl 2-{3-[(tert-Butyldimethylsilyl)oxy]cyclobutylidene}acetate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 270.44 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Ethyl 2-{3-[(tert-Butyldimethylsilyl)oxy]cyclobutylidene}acetate 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.
