Chemical Structure
Description
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.
4-(chloromethyl)-[1,3]dioxolo[4,5-c]pyridine (CAS 139645-24-2), molecular formula C7H12ClNO2 and molecular weight 177.63 g/mol, is a CATO reference standard with documented purity and traceability.
4-(chloromethyl)-[1,3]dioxolo[4,5-c]pyridine (C7H12ClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
CATO manufactures 4-(chloromethyl)-[1,3]dioxolo[4,5-c]pyridine 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.
