2-3-O-Isopropylidene-L-gulonic acid-1-4-lactone CAS 94840-08-1

Description

As a certified reference material (CRM), 2-3-O-Isopropylidene-L-gulonic acid-1-4-lactone 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.

2-3-O-Isopropylidene-L-gulonic acid-1-4-lactone (CAS 94840-08-1) is a high-purity analytical reference standard with the molecular formula C9H14O6 and a molecular weight of 218.20 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-3-O-Isopropylidene-L-gulonic acid-1-4-lactone is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.20 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).

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.
