Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 237.25 g/mol gives tert-Butyl 2-methyl-5-nitrobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies tert-Butyl 2-methyl-5-nitrobenzoate (CAS 873005-25-5), a certified reference material (molecular formula C12H15NO4, MW 237.25 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, tert-Butyl 2-methyl-5-nitrobenzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), tert-Butyl 2-methyl-5-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.
