Tert-butyl 4-bromo-3,5-dimethylbenzoate CAS 440105-29-3

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 4-bromo-3,5-dimethylbenzoate.

Tert-butyl 4-bromo-3,5-dimethylbenzoate (CAS 440105-29-3), molecular formula C13H17BrO2 and molecular weight 285.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H17BrO2, Tert-butyl 4-bromo-3,5-dimethylbenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Tert-butyl 4-bromo-3,5-dimethylbenzoate 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.
