Description
Compared with other compounds in its class, the molecular weight of 176.17 g/mol gives (5-Ethynylbenzo[d][1,3]dioxol-4-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(5-Ethynylbenzo[d][1,3]dioxol-4-yl)methanol (CAS 241813-21-8), molecular formula C10H8O3 and molecular weight 176.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (5-Ethynylbenzo[d][1,3]dioxol-4-yl)methanol (C10H8O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (5-Ethynylbenzo[d][1,3]dioxol-4-yl)methanol 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.
