Analytical Procedure Development and Proposed Established Conditions: A Case Study of a Mass Spectrometry Based NDSRI Analytical Procedure. J Pharm Sci 2024:S0022-3549(24)00266-1. [PMID: 39111548 DOI: 10.1016/j.xphs.2024.07.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 07/26/2024] [Accepted: 07/27/2024] [Indexed: 08/15/2024]
Abstract
With the finalization of the ICH Q14 Analytical Procedure Development guideline, how to apply enhanced approaches (such as analytical quality by design (AQbD)) to develop an analytical procedure, and to propose Established Conditions (ECs) and corresponding reporting categories, is increasingly being discussed. To gain practical experience in applying an enhanced approach for method development and identifying ECs, we developed, validated, and implemented an analytical procedure for a nitrosamine drug substance-related impurity (NDSRI). Here, as an example of the application of Q12 Lifecycle Management guideline principles in regards to analytical procedures, we briefly elaborate how: 1) the principles documented in the ICH Q14 guideline for analytical procedure development were applied, with the focus on identifying an Analytical Target Profile (ATP), knowledge management and risk assessment; 2) analytical procedure robustness according to the recommendations in ICH Q2(R2) Validation of Analytical Procedure guideline and Q14, were evaluated; and 3) mass spectrometry ECs and associated proposed reporting categories were proposed.

Wickens JR, Dominey AP. On-column trace-level formation of N-nitrosamine in a liquid chromatography-mass spectrometry analytical system. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2024; 38:e9691. [PMID: 38212653 DOI: 10.1002/rcm.9691] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 10/25/2023] [Accepted: 12/08/2023] [Indexed: 01/13/2024]
Abstract
A model reaction between di-n-butylamine and sodium nitrite was studied to investigate trace-level N-nitrosamine formation. Liquid chromatography-mass spectrometry (LC-MS) analysis of kinetic time points from an in-progress reaction showed a systematic offset in nitrosamine concentration between quenched and unquenched samples. By combining samples of amine and nitrite in the needle of the autosampler it was demonstrated that N-nitrosamine was formed in the LC-MS system. Further experimentation indicated that nitrosation was occurring on-column.
