Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (Z)-1-[(4-Cyano-5-methyl-1,2-thiazol-3-yl)sulfonyl]-N-phenylmethanecarbohydrazonoyl cyanide (CAS 337928-19-5), a certified reference material (molecular formula C13H9N5O2S2, MW 331.37 g/mol) for analytical method development and quality control.
Structurally, (Z)-1-[(4-Cyano-5-methyl-1,2-thiazol-3-yl)sulfonyl]-N-phenylmethanecarbohydrazonoyl cyanide (C13H9N5O2S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 331.37 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
