Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 226.70 g/mol gives 4-(Pentyloxy)benzoyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Pentyloxy)benzoyl chloride (CAS 36823-84-4), a certified reference material (molecular formula C12H15ClO2, MW 226.70 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Pentyloxy)benzoyl chloride (C12H15ClO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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. 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.
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.
