Chemical Structure
Description
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.
845781-47-7 5-(4-tert-Butylphenyl)-3-methyl-5-oxovaleric acid DTXSID00373827 (CAS 845781-47-7), molecular formula C16H22O3 and molecular weight 262.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 845781-47-7 5-(4-tert-Butylphenyl)-3-methyl-5-oxovaleric acid DTXSID00373827 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 262.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 845781-47-7 5-(4-tert-Butylphenyl)-3-methyl-5-oxovaleric acid DTXSID00373827 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.
