Chemical Structure

Iminodiacetic Acid CAS 142-73-4 chemical structure

Description

Iminodiacetic Acid (CAS 142-73-4) is a high-purity analytical reference standard with the molecular formula C4H7NO4 and a molecular weight of 133.10 g/mol.

Owing to a carbohydrate-derived structure, an amide group, Iminodiacetic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.10 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), Iminodiacetic 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.
