Chemical Structure

β,β-Trehalose CAS 499-23-0 chemical structure

Description

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.

β,β-Trehalose (CAS 499-23-0), molecular formula C12H22O11 and molecular weight 342.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, β,β-Trehalose is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

As a certified reference material (CRM), β,β-Trehalose 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.
