The occurrence of 302-04-5 CHEBI:18022 N#C-S(-) NCS- Rhodanid SCN(-) THIOCYANATE ION Thiozyanat [S-C#N](-) nitridosulfidocarbonate(1-) nitridothiocarbonate(1-) nitridothiocarbonate(IV) rhodanide thiocyanate thiocyanate ion (1-) is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
302-04-5 CHEBI:18022 N#C-S(-) NCS- Rhodanid SCN(-) THIOCYANATE ION Thiozyanat [S-C#N](-) nitridosulfidocarbonate(1-) nitridothiocarbonate(1-) nitridothiocarbonate(IV) rhodanide thiocyanate thiocyanate ion (1-) (CAS 302-04-5), molecular formula CNS and molecular weight 58.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 302-04-5 CHEBI:18022 N#C-S(-) NCS- Rhodanid SCN(-) THIOCYANATE ION Thiozyanat [S-C#N](-) nitridosulfidocarbonate(1-) nitridothiocarbonate(1-) nitridothiocarbonate(IV) rhodanide thiocyanate thiocyanate ion (1-) (CNS) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
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.
