Chemical Structure

ethyl 1-ethynylcyclopropanecarboxylate CAS 1509901-02-3 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.

ethyl 1-ethynylcyclopropanecarboxylate (CAS 1509901-02-3), molecular formula C8H10O2 and molecular weight 138.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, ethyl 1-ethynylcyclopropanecarboxylate is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures ethyl 1-ethynylcyclopropanecarboxylate 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.
