Chemical Structure

4-Bromoheptane CAS 998-93-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 179.10 g/mol gives 4-Bromoheptane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Bromoheptane (CAS 998-93-6), molecular formula C7H15Br and molecular weight 179.10 g/mol, is a CATO reference standard with documented purity and traceability.

4-Bromoheptane (C7H15Br) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Bromoheptane 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.
