Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,7-Disulfamoyl-9H-fluoren-9-ylidene)hydrazinecarbothioamide.
2-(2,7-Disulfamoyl-9H-fluoren-9-ylidene)hydrazinecarbothioamide (CAS 303059-60-1) is a high-purity analytical reference standard with the molecular formula C14H13N5O4S3 and a molecular weight of 411.48 g/mol.
2-(2,7-Disulfamoyl-9H-fluoren-9-ylidene)hydrazinecarbothioamide (C14H13N5O4S3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
