Chemical Structure
Description
The occurrence of 4-[(4-bromophenyl)sulfanyl]butanoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-[(4-bromophenyl)sulfanyl]butanoic acid (CAS 15115-76-1) is a high-purity analytical reference standard with the molecular formula PtC7H5O2C3H9NClH3N and a molecular weight of 427.79 g/mol.
The molecular framework of 4-[(4-bromophenyl)sulfanyl]butanoic acid (PtC7H5O2C3H9NClH3N) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-[(4-bromophenyl)sulfanyl]butanoic acid 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.
