Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 270.28 g/mol gives 4-Formyl-2-methoxyphenyl 4-methylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Formyl-2-methoxyphenyl 4-methylbenzoate (CAS 429621-85-2), molecular formula C16H14O4 and molecular weight 270.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Formyl-2-methoxyphenyl 4-methylbenzoate (C16H14O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 4-Formyl-2-methoxyphenyl 4-methylbenzoate 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.
