Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-(4-Bromophenyl)-4-(tert-butoxy)-4-oxobutanoic acid.
CATO supplies (S)-2-(4-Bromophenyl)-4-(tert-butoxy)-4-oxobutanoic acid (CAS 2615912-68-8), a certified reference material (molecular formula C14H17BrO4, MW 329.19 g/mol) for analytical method development and quality control.
Structurally, (S)-2-(4-Bromophenyl)-4-(tert-butoxy)-4-oxobutanoic acid (C14H17BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 329.19 g/mol, it falls into the moderately-high-molecular-weight range. 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.
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.
