Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 666.58 g/mol gives α-D-Maltotetraose distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies α-D-Maltotetraose (CAS 13086-23-2), a certified reference material (molecular formula C24H42O21, MW 666.58 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, α-D-Maltotetraose is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 666.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), α-D-Maltotetraose 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.
