Chemical Structure

(3-Bromopropyl)cyclobutane CAS 21782-49-0 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 (3-Bromopropyl)cyclobutane.

CATO supplies (3-Bromopropyl)cyclobutane (CAS 21782-49-0), a certified reference material (molecular formula C7H13Br, MW 177.08 g/mol) for analytical method development and quality control.

(3-Bromopropyl)cyclobutane (C7H13Br) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
