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 Trimethyl((tetrahydro-2H-pyran-4-yl)ethynyl)silane.
CATO supplies Trimethyl((tetrahydro-2H-pyran-4-yl)ethynyl)silane (CAS 1604039-54-4), a certified reference material (molecular formula C10H18OSi, MW 182.33 g/mol) for analytical method development and quality control.
Trimethyl((tetrahydro-2H-pyran-4-yl)ethynyl)silane (C10H18OSi) contains a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
