Compared with other compounds in its class, the molecular weight of 364.70 g/mol gives 1,1,1,3,5,5,5-Heptamethyl-3-(3-((tetrahydrofuran-2-yl)methoxy)propyl)trisiloxane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,1,1,3,5,5,5-Heptamethyl-3-(3-((tetrahydrofuran-2-yl)methoxy)propyl)trisiloxane (CAS 1361237-41-3), molecular formula C15H36O4Si3 and molecular weight 364.70 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 1,1,1,3,5,5,5-Heptamethyl-3-(3-((tetrahydrofuran-2-yl)methoxy)propyl)trisiloxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 364.70 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.
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), 1,1,1,3,5,5,5-Heptamethyl-3-(3-((tetrahydrofuran-2-yl)methoxy)propyl)trisiloxane 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.
