Chemical Structure

1,2-Cyclohexylenedinitrilotetraacetic acid CAS 482-54-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 346.33 g/mol gives 1,2-Cyclohexylenedinitrilotetraacetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2-Cyclohexylenedinitrilotetraacetic acid (CAS 482-54-2), molecular formula C14H22N2O8 and molecular weight 346.33 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1,2-Cyclohexylenedinitrilotetraacetic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 1,2-Cyclohexylenedinitrilotetraacetic acid 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.
