Description

As a certified reference material (CRM), β-D-Arabinopyranoside, phenylmethyl 2,3-O-[(1S,2S)-1,2-dimethoxy-1,2-dimethyl-1,2-ethanediyl]- 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.

β-D-Arabinopyranoside, phenylmethyl 2,3-O-[(1S,2S)-1,2-dimethoxy-1,2-dimethyl-1,2-ethanediyl]- (CAS 887370-09-4) is a high-purity analytical reference standard with the molecular formula C18H26O7 and a molecular weight of 354.39 g/mol.

β-D-Arabinopyranoside, phenylmethyl 2,3-O-[(1S,2S)-1,2-dimethoxy-1,2-dimethyl-1,2-ethanediyl]- (C18H26O7) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
