Chemical Structure
Description
2-(7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acetic acid (CAS 915921-98-1), molecular formula C10H9ClO4 and molecular weight 228.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2-(7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.63 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.
CATO manufactures 2-(7-Chloro-2,3-dihydrobenzo[b][1,4]dioxin-6-yl)acetic acid 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.
