1-oxo-3H-isobenzofuran-5-carbaldehyde CAS 333333-34-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-oxo-3H-isobenzofuran-5-carbaldehyde.

1-oxo-3H-isobenzofuran-5-carbaldehyde (CAS 333333-34-9), molecular formula C9H12O3 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.

1-oxo-3H-isobenzofuran-5-carbaldehyde (C9H12O3) 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.

CATO manufactures 1-oxo-3H-isobenzofuran-5-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
