Ethyl 5-(3-bromo-4-methylphenyl)-5-oxopentanoate CAS 898776-84-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 5-(3-bromo-4-methylphenyl)-5-oxopentanoate.

Ethyl 5-(3-bromo-4-methylphenyl)-5-oxopentanoate (CAS 898776-84-6) is a high-purity analytical reference standard with the molecular formula C14H17BrO3 and a molecular weight of 313.19 g/mol.

Based on its molecular formula C14H17BrO3, Ethyl 5-(3-bromo-4-methylphenyl)-5-oxopentanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 313.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
