Chemical Structure

Heptanoic Anhydride CAS 626-27-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 242.35 g/mol gives Heptanoic Anhydride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Heptanoic Anhydride (CAS 626-27-7), a certified reference material (molecular formula C14H26O3, MW 242.35 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H26O3, Heptanoic Anhydride contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 242.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Heptanoic Anhydride 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.
