Chemical Structure

1,3-Dimethylparabanic Acid CAS 5176-82-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,3-Dimethylparabanic Acid (CAS 5176-82-9) is a high-purity analytical reference standard with the molecular formula C5H6N2O3 and a molecular weight of 142.11 g/mol.

Structurally, 1,3-Dimethylparabanic Acid (C5H6N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 142.11 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 1,3-Dimethylparabanic Acid 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.
