Chemical Structure
Description
Methyl 5-((tert-butyldimethylsilyl)oxy)-2-methylbenzoate (CAS 866028-37-7), molecular formula C15H24O3Si and molecular weight 280.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 5-((tert-butyldimethylsilyl)oxy)-2-methylbenzoate (C15H24O3Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Methyl 5-((tert-butyldimethylsilyl)oxy)-2-methylbenzoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
