Chemical Structure

Glucosamine Impurity 9 CAS 98-01-1 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Glucosamine Impurity 9 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.08 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).

Glucosamine Impurity 9 (CAS 98-01-1) is a certified pharmaceutical impurity reference standard with the molecular formula C5H4O2 and a molecular weight of 96.08 g/mol.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Glucosamine Impurity 9 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.
