Chemical Structure
Description
CATO supplies 8-((Trimethylsilyl)ethynyl)-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine (CAS 1246088-47-0), a certified reference material (molecular formula C12H15NO2Si, MW 233.34 g/mol) for analytical method development and quality control.
8-((Trimethylsilyl)ethynyl)-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine (C12H15NO2Si) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
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), 8-((Trimethylsilyl)ethynyl)-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine 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.
