1-Bromo-4,4-dimethyl-2-pentyne CAS 52323-99-6

Description

The occurrence of 1-Bromo-4,4-dimethyl-2-pentyne is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Bromo-4,4-dimethyl-2-pentyne (CAS 52323-99-6), molecular formula C7H11Br and molecular weight 175.07 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H11Br, 1-Bromo-4,4-dimethyl-2-pentyne contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 175.07 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.
