Description
CATO supplies 6-Benzyl-2,4-dichloro-8,8-difluoro-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine (CAS 1255666-47-7), a certified reference material (molecular formula C14H11Cl2F2N3, MW 330.16 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 6-Benzyl-2,4-dichloro-8,8-difluoro-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 330.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 6-Benzyl-2,4-dichloro-8,8-difluoro-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine 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.
