1159977-16-8 4-(4-Bromo-1-butyn-1-yl)-alpha,alpha-dimethyl-benzeneacetic Acid Methyl Ester CAS 1159977-16-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 309.20 g/mol gives 1159977-16-8 4-(4-Bromo-1-butyn-1-yl)-alpha,alpha-dimethyl-benzeneacetic Acid Methyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1159977-16-8 4-(4-Bromo-1-butyn-1-yl)-alpha,alpha-dimethyl-benzeneacetic Acid Methyl Ester (CAS 1159977-16-8), a certified reference material (molecular formula C15H17BrO2, MW 309.20 g/mol) for analytical method development and quality control.

The molecular framework of 1159977-16-8 4-(4-Bromo-1-butyn-1-yl)-alpha,alpha-dimethyl-benzeneacetic Acid Methyl Ester (C15H17BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
