Chemical Structure
Description
As a certified reference material (CRM), 2-(4-(Cyclopropylsulfonyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane 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.
2-(4-(Cyclopropylsulfonyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (CAS 648906-27-8) is a high-purity analytical reference standard with the molecular formula C15H21BO4S and a molecular weight of 308.20 g/mol.
The molecular framework of 2-(4-(Cyclopropylsulfonyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (C15H21BO4S) is characterized by a sulfone group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
