The molecular framework of 2-(4-tert-butylphenoxy)acetyl chloride 2-(4-tert-butylphenoxy)ethanoyl chloride 90734-55-7 A843628 (C12H21ClO2) is characterized by 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.
2-(4-tert-butylphenoxy)acetyl chloride 2-(4-tert-butylphenoxy)ethanoyl chloride 90734-55-7 A843628 (CAS 90734-55-7), molecular formula C12H21ClO2 and molecular weight 232.75 g/mol, is a CATO reference standard with documented purity and traceability.
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.
