CATO manufactures 4-(2-((1-Methyl-1h-tetrazol-5-yl)thio)ethoxy)benzonitrile 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.
4-(2-((1-Methyl-1h-tetrazol-5-yl)thio)ethoxy)benzonitrile (CAS 851631-06-6), molecular formula C11H11N5OS and molecular weight 261.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-(2-((1-Methyl-1h-tetrazol-5-yl)thio)ethoxy)benzonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
