1,1-Bis(bromomethyl)cyclopentane CAS 68499-28-5

Description

The occurrence of 1,1-Bis(bromomethyl)cyclopentane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1-Bis(bromomethyl)cyclopentane (CAS 68499-28-5), molecular formula C7H12Br2 and molecular weight 255.98 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,1-Bis(bromomethyl)cyclopentane (C7H12Br2) is characterized by bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 1,1-Bis(bromomethyl)cyclopentane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
