Chemical Structure
Description
The occurrence of 2-Bromo-2-propylpentanoic Acid Ethyl Ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-2-propylpentanoic Acid Ethyl Ester (CAS 99174-91-1), molecular formula C10H19BrO2 and molecular weight 251.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H19BrO2, 2-Bromo-2-propylpentanoic Acid Ethyl Ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 251.16 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.
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), 2-Bromo-2-propylpentanoic Acid Ethyl Ester 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.
