Chemical Structure

Rac-(1r,2r)-2-bromocyclohexan-1-ol, trans CAS 2425-33-4 chemical structure

Description

Rac-(1r,2r)-2-bromocyclohexan-1-ol, trans (CAS 2425-33-4), molecular formula C6H11BrO and molecular weight 179.05 g/mol, is a CATO reference standard with documented purity and traceability.

Rac-(1r,2r)-2-bromocyclohexan-1-ol, trans (C6H11BrO) contains a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), Rac-(1r,2r)-2-bromocyclohexan-1-ol, trans 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.
