Pyridine, 4-chloro-2-(1-methyl-2-propyn-1-yl)- CAS 2354798-06-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pyridine, 4-chloro-2-(1-methyl-2-propyn-1-yl)-.

Pyridine, 4-chloro-2-(1-methyl-2-propyn-1-yl)- (CAS 2354798-06-2), molecular formula C9H8ClN and molecular weight 165.62 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Pyridine, 4-chloro-2-(1-methyl-2-propyn-1-yl)- (C9H8ClN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
