4-Methyl-2-(trimethylsilyl)phenyl trifluoromethanesulfonate is associated with CAS 262373-15-9 and formula C11H15F3O3SSi. PubChem maps the registry number to a single record, CID 11449792, and reports molecular weight 312.38. The verified connectivity is SMILES CC1=CC(=C(C=C1)OS(=O)(=O)C(F)(F)F)[Si](C)(C)C, with InChIKey SKLVYEYSGSTOFD-UHFFFAOYSA-N identifying the same graph.
The phenyl ring bears an oxygen-linked trifluoromethanesulfonate group as its principal attachment. A trimethylsilyl substituent occupies the adjacent 2 position, and a methyl group lies at position 4. The three fluorines belong to the same carbon bound to sulfur, while all three oxygens form the aryl sulfonate connection and two sulfur-oxygen bonds. Silicon carries three methyl groups in addition to its aryl bond. These placements distinguish the record from regioisomeric methyl or silyl phenyl triflates sharing the elemental formula.
For an exact Rlavie inquiry, provide CAS 262373-15-9, the full positional name, and the requested quantity. A MOL or SDF structure file should accompany the request so its graph can be matched with PubChem CID 11449792, SMILES CC1=CC(=C(C=C1)OS(=O)(=O)C(F)(F)F)[Si](C)(C)C, and InChIKey SKLVYEYSGSTOFD-UHFFFAOYSA-N. Before request-specific information is reviewed, confirm the ortho trimethylsilyl group, para methyl group, and oxygen-bound trifluoromethanesulfonate. The abbreviated phrase “silylated phenyl triflate” is useful only as a search label because it does not preserve those locants. That context matters.
