Compared with other compounds in its class, the molecular weight of 243.64 g/mol gives Ethyl 5-chloro-4-methyl-2-nitrobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 5-chloro-4-methyl-2-nitrobenzoate (CAS 1805129-59-2), a certified reference material (molecular formula C10H10ClNO4, MW 243.64 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 5-chloro-4-methyl-2-nitrobenzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 5-chloro-4-methyl-2-nitrobenzoate 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.
