Chemical Structure
Description
3-[5-(Methylsulfanyl)-1H-1,2,3,4-tetrazol-1-yl]aniline hydrochloride (CAS 1172981-09-7), molecular formula C8H9N5SHCl and molecular weight 243.71 g/mol, is a CATO reference standard with documented purity and traceability.
3-[5-(Methylsulfanyl)-1H-1,2,3,4-tetrazol-1-yl]aniline hydrochloride (C8H9N5SHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
