Description

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

6-[(2-Amino-4-chlorophenyl)amino]-2,2-dimethyl-2,3-dihydro-4H-pyran-4-one (CAS 1216774-91-2), molecular formula C13H15ClN2O2 and molecular weight 266.72 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, chlorine substitution, 6-[(2-Amino-4-chlorophenyl)amino]-2,2-dimethyl-2,3-dihydro-4H-pyran-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.72 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.

As a certified reference material (CRM), 6-[(2-Amino-4-chlorophenyl)amino]-2,2-dimethyl-2,3-dihydro-4H-pyran-4-one 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.
