Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 21198-18-5 4N2C7UO813 4-Cyclohexylthiosemicarbazide Hydrazinecarbothioamide, N-cyclohexyl- N-Cyclohexylhydrazinecarbothioamide N-Cyclohexylthiosemicarbazide NSC 82337 Semicarbazide, 4-cyclohexyl-3-thio- UNII-4N2C7UO813.

21198-18-5 4N2C7UO813 4-Cyclohexylthiosemicarbazide Hydrazinecarbothioamide, N-cyclohexyl- N-Cyclohexylhydrazinecarbothioamide N-Cyclohexylthiosemicarbazide NSC 82337 Semicarbazide, 4-cyclohexyl-3-thio- UNII-4N2C7UO813 (CAS 21198-18-5) is a high-purity analytical reference standard with the molecular formula C7H15N3S and a molecular weight of 173.28 g/mol.

The molecular framework of 21198-18-5 4N2C7UO813 4-Cyclohexylthiosemicarbazide Hydrazinecarbothioamide, N-cyclohexyl- N-Cyclohexylhydrazinecarbothioamide N-Cyclohexylthiosemicarbazide NSC 82337 Semicarbazide, 4-cyclohexyl-3-thio- UNII-4N2C7UO813 (C7H15N3S) is characterized by a nitrile group, 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.
