8-Formyl-4-methylumbelliferone CAS 14003-96-4

Description

The occurrence of 8-Formyl-4-methylumbelliferone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

8-Formyl-4-methylumbelliferone (CAS 14003-96-4), molecular formula C11H8O4 and molecular weight 204.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 8-Formyl-4-methylumbelliferone (C11H8O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 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).

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), 8-Formyl-4-methylumbelliferone 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.
