Chemical Structure
Description
Tert-butyl (R)-4-bromo-2-methyl-2-(methylsulfonyl)butanoate (CAS 1678527-71-3) is a high-purity analytical reference standard with the molecular formula C10H19BrO4S and a molecular weight of 315.22 g/mol.
The molecular framework of Tert-butyl (R)-4-bromo-2-methyl-2-(methylsulfonyl)butanoate (C10H19BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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. 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), Tert-butyl (R)-4-bromo-2-methyl-2-(methylsulfonyl)butanoate 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.
