Chemical Structure

Ammonium 2-oxopentanedioate CAS 15303-07-8 chemical structure

Description

Ammonium 2-oxopentanedioate (CAS 15303-07-8), molecular formula C5H4O5H4N and molecular weight 162.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carbohydrate-derived structure, an amide group, Ammonium 2-oxopentanedioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.12 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.

CATO manufactures Ammonium 2-oxopentanedioate 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.
