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.
1-(3-Chloro-3-methylbut-1-yn-1-yl)-4-methoxybenzene (CAS 75111-06-7), molecular formula C12H13ClO and molecular weight 208.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3-Chloro-3-methylbut-1-yn-1-yl)-4-methoxybenzene (C12H13ClO) is characterized by 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.
CATO manufactures 1-(3-Chloro-3-methylbut-1-yn-1-yl)-4-methoxybenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
