Chemical Structure

Syringaldehyde CAS 134-96-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 182.17 g/mol gives Syringaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Syringaldehyde (CAS 134-96-3) is a high-purity analytical reference standard with the molecular formula C9H10O4 and a molecular weight of 182.17 g/mol.

Structurally, Syringaldehyde (C9H10O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 182.17 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
