Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2,5-Dimethylphenyl)-2-methyl-1-butene.
4-(2,5-Dimethylphenyl)-2-methyl-1-butene (CAS 951891-90-0), molecular formula C13H18 and molecular weight 174.28 g/mol, is a CATO reference standard with documented purity and traceability.
4-(2,5-Dimethylphenyl)-2-methyl-1-butene (C13H18) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 4-(2,5-Dimethylphenyl)-2-methyl-1-butene 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.
