18791-21-4 2-Pyridinecarboxamide, 3-hydroxy-N-[(2Z,5R,6S,9S,10S,11R)-10-hydroxy-5,11-dimethyl-2-(1-methylpropylidene)-3,7,12-trioxo-9-(3-pyridinylmethyl)-1,4-dioxa-8-azacyclododec-6-yl]- 3-hydroxy-N-[(2Z,5R,6S,9S,10R,11R)-10-hydroxy-5,11-dimethyl-2-(1-methylpropylidene)-3,7,12-trioxo-9-(3-pyridylmethyl)-1,4-dioxa-8-azacyclododec-6-yl]pyridine-2-carboxamide NSC246134 Pyridomycin (CAS 18791-21-4), molecular formula C27H32N4O8 and molecular weight 540.56 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C27H32N4O8, 18791-21-4 2-Pyridinecarboxamide, 3-hydroxy-N-[(2Z,5R,6S,9S,10S,11R)-10-hydroxy-5,11-dimethyl-2-(1-methylpropylidene)-3,7,12-trioxo-9-(3-pyridinylmethyl)-1,4-dioxa-8-azacyclododec-6-yl]- 3-hydroxy-N-[(2Z,5R,6S,9S,10R,11R)-10-hydroxy-5,11-dimethyl-2-(1-methylpropylidene)-3,7,12-trioxo-9-(3-pyridylmethyl)-1,4-dioxa-8-azacyclododec-6-yl]pyridine-2-carboxamide NSC246134 Pyridomycin contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 540.56 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 18791-21-4 2-Pyridinecarboxamide, 3-hydroxy-N-[(2Z,5R,6S,9S,10S,11R)-10-hydroxy-5,11-dimethyl-2-(1-methylpropylidene)-3,7,12-trioxo-9-(3-pyridinylmethyl)-1,4-dioxa-8-azacyclododec-6-yl]- 3-hydroxy-N-[(2Z,5R,6S,9S,10R,11R)-10-hydroxy-5,11-dimethyl-2-(1-methylpropylidene)-3,7,12-trioxo-9-(3-pyridylmethyl)-1,4-dioxa-8-azacyclododec-6-yl]pyridine-2-carboxamide NSC246134 Pyridomycin 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.
