Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, Gold, trichloro(2-methylbenzothiazole-N3)-, (SP-4-2)- is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Gold, trichloro(2-methylbenzothiazole-N3)-, (SP-4-2)- (CAS 134536-75-7), molecular formula C8H7AuCl3NS and molecular weight 452.54 g/mol, is a CATO reference standard with documented purity and traceability.
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.
