Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-butyl benzyl(2,6-dichloropyrimidin-4-yl)carbamate.
tert-butyl benzyl(2,6-dichloropyrimidin-4-yl)carbamate (CAS 270929-33-4), molecular formula C16H17Cl2N3O2 and molecular weight 354.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-butyl benzyl(2,6-dichloropyrimidin-4-yl)carbamate (C16H17Cl2N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 354.23 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), tert-butyl benzyl(2,6-dichloropyrimidin-4-yl)carbamate 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.
