Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.63 g/mol gives Ethyl 2-chloro-4-methylnicotinate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 2-chloro-4-methylnicotinate (CAS 50840-02-3), a certified reference material (molecular formula C9H10ClNO2, MW 199.63 g/mol) for analytical method development and quality control.
Ethyl 2-chloro-4-methylnicotinate (C9H10ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 2-chloro-4-methylnicotinate 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.
