Chemical Structure
Description
2-Methylbutanoic acid compound with 6-methyl-1H-benzimidazole-2-thiol (1:1) (CAS 884242-13-1) is a high-purity analytical reference standard with the molecular formula C8H8N2SC5H10O2 and a molecular weight of 266.36 g/mol.
2-Methylbutanoic acid compound with 6-methyl-1H-benzimidazole-2-thiol (1:1) (C8H8N2SC5H10O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 2-Methylbutanoic acid compound with 6-methyl-1H-benzimidazole-2-thiol (1:1) 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.
