1-Bromo-11-iodoundecane CAS 139123-69-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-11-iodoundecane.

1-Bromo-11-iodoundecane (CAS 139123-69-6), molecular formula C11H22BrI and molecular weight 361.10 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to bromine/iodine substitution, 1-Bromo-11-iodoundecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-Bromo-11-iodoundecane 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.
