(R)-2-(5-bromothiophen-2-yl)-4-(tert-butoxy)-4-oxobutanoic acid CAS 2615912-72-4

Description

The occurrence of (R)-2-(5-bromothiophen-2-yl)-4-(tert-butoxy)-4-oxobutanoic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(R)-2-(5-bromothiophen-2-yl)-4-(tert-butoxy)-4-oxobutanoic acid (CAS 2615912-72-4), molecular formula C12H15BrO4S and molecular weight 335.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (R)-2-(5-bromothiophen-2-yl)-4-(tert-butoxy)-4-oxobutanoic acid (C12H15BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
