7-Chloro-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine-6-carbaldehyde CAS 1346447-08-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Chloro-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine-6-carbaldehyde.

CATO supplies 7-Chloro-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine-6-carbaldehyde (CAS 1346447-08-2), a certified reference material (molecular formula C8H6ClNO3, MW 199.59 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H6ClNO3, 7-Chloro-2,3-dihydro-[1,4]dioxino[2,3-b]pyridine-6-carbaldehyde contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 199.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
