Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,8-dichloro-1,7-naphthyridine.
CATO supplies 4,8-dichloro-1,7-naphthyridine (CAS 1279894-03-9), a certified reference material (molecular formula C8H14Cl2N2, MW 209.12 g/mol) for analytical method development and quality control.
4,8-dichloro-1,7-naphthyridine (C8H14Cl2N2) contains a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 4,8-dichloro-1,7-naphthyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
