Chemical Structure

2-Ethynyl-5-methylbenzaldehyde CAS 1309565-96-5 chemical structure

Description

CATO manufactures 2-Ethynyl-5-methylbenzaldehyde 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.

2-Ethynyl-5-methylbenzaldehyde (CAS 1309565-96-5), molecular formula C10H8O and molecular weight 144.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2-Ethynyl-5-methylbenzaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.17 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).

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.
