Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 70695-02-2 Nargenicin A1 Nodusmicin, 9-(1H-pyrrole-2-carboxylate) NSC 355066.

70695-02-2 Nargenicin A1 Nodusmicin, 9-(1H-pyrrole-2-carboxylate) NSC 355066 (CAS 70695-02-2) is a high-purity analytical reference standard with the molecular formula C28H37NO8 and a molecular weight of 515.60 g/mol.

Based on its molecular formula C28H37NO8, 70695-02-2 Nargenicin A1 Nodusmicin, 9-(1H-pyrrole-2-carboxylate) NSC 355066 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 515.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
