Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 109.57 g/mol gives Cyclopropane-d5-carbonyl Chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cyclopropane-d5-carbonyl Chloride (CAS 1219794-96-3) is a high-purity analytical reference standard with the molecular formula C4D5ClO and a molecular weight of 109.57 g/mol.
Structurally, Cyclopropane-d5-carbonyl Chloride (C4D5ClO) contains deuterium isotope labeling, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 109.57 g/mol, it falls into the low-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), Cyclopropane-d5-carbonyl Chloride 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.
