5454-83-1 Methyl 5-bromovalerate Pentanoic acid, 5-bromo-, methyl ester Valeric acid, 5-bromo-, methyl ester (8CI) 5-Bromovaleric acid methyl ester EINECS 226-709-7 Methyl omega-bromopentanoate Methyl 5-bromopentanoate NSC 23228 CAS 5454-83-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5454-83-1 Methyl 5-bromovalerate Pentanoic acid, 5-bromo-, methyl ester Valeric acid, 5-bromo-, methyl ester (8CI) 5-Bromovaleric acid methyl ester EINECS 226-709-7 Methyl omega-bromopentanoate Methyl 5-bromopentanoate NSC 23228.

5454-83-1 Methyl 5-bromovalerate Pentanoic acid, 5-bromo-, methyl ester Valeric acid, 5-bromo-, methyl ester (8CI) 5-Bromovaleric acid methyl ester EINECS 226-709-7 Methyl omega-bromopentanoate Methyl 5-bromopentanoate NSC 23228 (CAS 5454-83-1), molecular formula C6H11BrO2 and molecular weight 195.05 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C6H11BrO2, 5454-83-1 Methyl 5-bromovalerate Pentanoic acid, 5-bromo-, methyl ester Valeric acid, 5-bromo-, methyl ester (8CI) 5-Bromovaleric acid methyl ester EINECS 226-709-7 Methyl omega-bromopentanoate Methyl 5-bromopentanoate NSC 23228 contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 195.05 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.

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.
