Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Fluoro-2,4,5-trimethylbenzene.
1-Fluoro-2,4,5-trimethylbenzene (CAS 400-01-1), molecular formula C9H11F and molecular weight 138.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Fluoro-2,4,5-trimethylbenzene (C9H11F) contains fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 138.18 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Fluoro-2,4,5-trimethylbenzene 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.
