1-(2,3-Dichlorophenyl)-4,4-dimethyl-1,4-dihydropyrimidine-2-thiol CAS 1142212-29-0

Description

As a certified reference material (CRM), 1-(2,3-Dichlorophenyl)-4,4-dimethyl-1,4-dihydropyrimidine-2-thiol 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.

1-(2,3-Dichlorophenyl)-4,4-dimethyl-1,4-dihydropyrimidine-2-thiol (CAS 1142212-29-0), molecular formula C12H12Cl2N2S and molecular weight 287.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution, 1-(2,3-Dichlorophenyl)-4,4-dimethyl-1,4-dihydropyrimidine-2-thiol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
