spiro[3.3]heptane-2,6-dione CAS 20061-23-8 chemical structure

Description

CATO manufactures spiro[3.3]heptane-2,6-dione 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.

CATO supplies spiro[3.3]heptane-2,6-dione (CAS 20061-23-8), a certified reference material (molecular formula C7H8O2, MW 124.14 g/mol) for analytical method development and quality control.

spiro[3.3]heptane-2,6-dione (C7H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
