Chemical Structure
Description
The occurrence of Trifluoro-methanesulfonic acid tripropylsilyl ester is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Trifluoro-methanesulfonic acid tripropylsilyl ester (CAS 301338-15-8), molecular formula C10H21F3O3SSi and molecular weight 306.42 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Trifluoro-methanesulfonic acid tripropylsilyl ester (C10H21F3O3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 306.42 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Trifluoro-methanesulfonic acid tripropylsilyl ester 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.
