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.
CATO supplies (4AS,6S,7S,7aS)-2,2,2',2'-tetramethyltetrahydrospiro[furo[3,2-d][1,3]dioxine-6,4'-[1,3]dioxolan]-7-ol (CAS 32717-65-0), a certified reference material (molecular formula C12H20O6, MW 260.28 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, (4AS,6S,7S,7aS)-2,2,2',2'-tetramethyltetrahydrospiro[furo[3,2-d][1,3]dioxine-6,4'-[1,3]dioxolan]-7-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.28 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).
CATO manufactures (4AS,6S,7S,7aS)-2,2,2',2'-tetramethyltetrahydrospiro[furo[3,2-d][1,3]dioxine-6,4'-[1,3]dioxolan]-7-ol under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
