Chemical Structure
Description
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Methyl 3-methoxy-5-(3-methylphenyl)benzoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Methyl 3-methoxy-5-(3-methylphenyl)benzoate (CAS 1820603-40-4), molecular formula C16H16O3 and molecular weight 256.30 g/mol, is a CATO reference standard with documented purity and traceability.
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), Methyl 3-methoxy-5-(3-methylphenyl)benzoate 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.
