Methyl 3-formyl-2-hydroxybenzoate CAS 3775-05-1

Description

The occurrence of Methyl 3-formyl-2-hydroxybenzoate 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.

Methyl 3-formyl-2-hydroxybenzoate (CAS 3775-05-1), molecular formula C9H8O4 and molecular weight 180.16 g/mol, is a CATO reference standard with documented purity and traceability.

Methyl 3-formyl-2-hydroxybenzoate (C9H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Methyl 3-formyl-2-hydroxybenzoate 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.
