Description
As a certified reference material (CRM), 2,2,5,5-Tetramethylpyrrolidine hydrochloride 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.
2,2,5,5-Tetramethylpyrrolidine hydrochloride (CAS 4567-23-1), molecular formula C8H18NCl and molecular weight 163.69 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,2,5,5-Tetramethylpyrrolidine hydrochloride (C8H18NCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 163.69 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
