Description

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.

2,2 inverted exclamation marka-Biquinoline-4,4 inverted exclamation marka-dicarboxylic acid disodium salt; 4,4 inverted exclamation marka-Dicarboxy-2,2 inverted exclamation marka-biquinoline disodium salt; BCA; Disodium 2,2 inverted exclamation marka-biquinoline-4,4 inverted exclamation marka-dicarboxylate 979-88-4 AB1010052 (CAS 979-88-4) is a high-purity analytical reference standard with the molecular formula C20H30N2O4NaH2O and a molecular weight of 403.47 g/mol.

Based on its molecular formula C20H30N2O4NaH2O, 2,2 inverted exclamation marka-Biquinoline-4,4 inverted exclamation marka-dicarboxylic acid disodium salt; 4,4 inverted exclamation marka-Dicarboxy-2,2 inverted exclamation marka-biquinoline disodium salt; BCA; Disodium 2,2 inverted exclamation marka-biquinoline-4,4 inverted exclamation marka-dicarboxylate 979-88-4 AB1010052 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.47 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
