Description
JI046KHA6S 4604-72-2 Pyrazinethiocarboxamide Pyrazinecarbothioamide (9CI) Pyrazinecarboxamide, thio- 5-25-04-00191 (Beilstein Handbook Reference) BRN 0002638 NSC 18377 Pyrazinecarboxylic acid thioamide 2-Pyrazinethiocarboxamide Thiopyrazinamide UNII-JI046KHA6S (CAS 4604-72-2) is a high-purity analytical reference standard with the molecular formula C5H11N3S and a molecular weight of 145.23 g/mol.
The molecular framework of JI046KHA6S 4604-72-2 Pyrazinethiocarboxamide Pyrazinecarbothioamide (9CI) Pyrazinecarboxamide, thio- 5-25-04-00191 (Beilstein Handbook Reference) BRN 0002638 NSC 18377 Pyrazinecarboxylic acid thioamide 2-Pyrazinethiocarboxamide Thiopyrazinamide UNII-JI046KHA6S (C5H11N3S) 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.
As a certified reference material (CRM), JI046KHA6S 4604-72-2 Pyrazinethiocarboxamide Pyrazinecarbothioamide (9CI) Pyrazinecarboxamide, thio- 5-25-04-00191 (Beilstein Handbook Reference) BRN 0002638 NSC 18377 Pyrazinecarboxylic acid thioamide 2-Pyrazinethiocarboxamide Thiopyrazinamide UNII-JI046KHA6S meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
