3033-82-7 8-Chloro-2-methylquinoline NSC-4982 NSC4982 Quinaldine, 8-chloro- Quinoline, 8-chloro-2-methyl- CAS 3033-82-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3033-82-7 8-Chloro-2-methylquinoline NSC-4982 NSC4982 Quinaldine, 8-chloro- Quinoline, 8-chloro-2-methyl-.

3033-82-7 8-Chloro-2-methylquinoline NSC-4982 NSC4982 Quinaldine, 8-chloro- Quinoline, 8-chloro-2-methyl- (CAS 3033-82-7) is a high-purity analytical reference standard with the molecular formula C10H18ClN and a molecular weight of 187.71 g/mol.

Based on its molecular formula C10H18ClN, 3033-82-7 8-Chloro-2-methylquinoline NSC-4982 NSC4982 Quinaldine, 8-chloro- Quinoline, 8-chloro-2-methyl- contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 187.71 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.

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.
