Description
As a certified reference material (CRM), Methyl 3-hexyl-[2,2'-bithiophene]-5-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Methyl 3-hexyl-[2,2'-bithiophene]-5-carboxylate (CAS 918826-01-4) is a high-purity analytical reference standard with the molecular formula C16H20O2S2 and a molecular weight of 308.46 g/mol.
Methyl 3-hexyl-[2,2'-bithiophene]-5-carboxylate (C16H20O2S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
