Chemical Structure
Description
5-(Benzyloxy)-3-chloropyridazine (CAS 1346691-32-4), molecular formula C11H9ClN2O and molecular weight 220.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 5-(Benzyloxy)-3-chloropyridazine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 220.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 5-(Benzyloxy)-3-chloropyridazine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
