Chemical Structure

3a-4b-Galactotriose CAS 56038-36-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 504.44 g/mol gives 3a-4b-Galactotriose distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3a-4b-Galactotriose (CAS 56038-36-9), molecular formula C18H32O16 and molecular weight 504.44 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3a-4b-Galactotriose is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 3a-4b-Galactotriose 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.
