Chemical Structure
Description
The molecular framework of (3-Chloro-3-methylbut-1-yn-1-yl)benzene (C11H11Cl) is characterized by 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(3-Chloro-3-methylbut-1-yn-1-yl)benzene (CAS 3355-29-1), molecular formula C11H11Cl and molecular weight 178.66 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.
