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 tert-Butyl 2-(4-bromo-2-iodophenoxy)acetate.
CATO supplies tert-Butyl 2-(4-bromo-2-iodophenoxy)acetate (CAS 1240288-35-0), a certified reference material (molecular formula C12H14BrIO3, MW 413.05 g/mol) for analytical method development and quality control.
Structurally, tert-Butyl 2-(4-bromo-2-iodophenoxy)acetate (C12H14BrIO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 413.05 g/mol, it falls into the moderately-high-molecular-weight range. 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), tert-Butyl 2-(4-bromo-2-iodophenoxy)acetate 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.
